Bridge bearings are structural devices installed between bridge substructures and superstructures. They transfer loads while allowing for movement. There are two main types: expansion bearings, which allow translational and rotational movement, and fixed bearings, which allow limited translational and rotational movement. Common bearing types include sliding, rocker and pin, roller, elastomeric, curved, pot, and disk bearings. Each has distinct structures, materials, and abilities to accommodate different load types and movements. Regular inspection and maintenance are important due to risks of corrosion and damage over time.
Bridge bearings are used to transfer forces from the superstructure to the substructure while allowing movements. Traditional bearings included pin, roller, rocker, and sliding metal bearings. Pin bearings allow rotation but not translation. Roller bearings allow longitudinal movement and restrict lateral and rotational movement using gearing. Rocker and pin bearings are used in steel bridges as they accommodate both rotational and translational movements. Sliding bearings use low-friction materials like PTFE to allow translation. Modern bearings include pot, laminated elastomeric, lead-rubber, and plain elastomeric bearings. AASHTO guidelines provide criteria for selecting suitable bearings based on required movements and load resistances

The simulation of a vehicles suspension system represents an important part of how the driver experiences ride quality. Without a suspension system, a vehicle acts in a stiff and uncomfortable way. The characteristics of a vehicles performance are dependent on the properties of the suspension. A model of this system would enable a manufacturer to test how certain changes to the properties change the behavior of the vehicle. This way they are able to see how the stiffness of the spring and damper in the suspension system affects the ride experience before building an actual car. This can also reduce the cost of development. The most basic suspension system consists of a spring and shock absorber and also includes the stiffness of the tire being used. More complex suspension systems consist of sensors that take into account and compensate for traction control, engine torque, steering, and braking systems.

A bearing is a device that supports load and reduces friction between moving parts. There are two main types: plain/slider bearings and rolling/anti-friction bearings. Rolling bearings use balls or rollers to create separation between surfaces and are more commonly used. Common bearing materials include metals, alloys, and some non-metals. Bearings must be properly selected, mounted, lubricated, and maintained to maximize their lifespan and prevent premature failure.
This document discusses problems that can arise during and after construction of flyover bridges and their solutions. It outlines objectives to identify common issues and provide fundamental knowledge on construction and maintenance. Key problems discussed include earthworks not being properly leveled and compacted, substandard materials used in concrete and steel works, bearing failures from issues like misalignment, corrosion and contamination, and general corrosion of reinforcement from water and chloride ingress. Solutions proposed are reducing excessive loads, using higher quality materials, preventing contamination, diverting corrosive fluids, ensuring proper alignment, and increasing bond strength between steel and concrete. Literature on related topics is also reviewed.
Bearings are used to support rotating shafts and come in different types depending on whether they are designed to withstand axial thrusts, radial loads, or both. The main bearing types are ball bearings, which use spheres, and cylindrical roller bearings, which use cylinders, with each type having different capacities for loads and misalignment. Deep groove ball bearings can withstand both radial and axial loads, while angular contact ball bearings have increased axial load capacity and self-aligning ball bearings are very tolerant of misalignment.

Post-tensioned concrete slabs can accommodate post-formed holes and openings through careful planning and execution. Smaller holes under 20mm diameter can often be cut without affecting tendons. Larger openings are possible if located between tendons to avoid cutting them. When tendons must be cut, strengthening and temporary supports are needed. Bonded tendon slabs can be altered similarly to reinforced concrete, with tendon bond redeveloping within 1m of cuts. Unbonded tendon slabs require detensioning or propping near cuts due to loss of prestress over the whole length. With proper engineering and specialist work, post-tensioned slabs can safely accommodate new openings.

The company's environmental policy aims to minimize waste and maximize reuse/recycling, maintain efficient energy and resource use, and encourage suppliers and employees to improve sustainability. The policy also covers promoting environmental awareness, controlling risks from hazardous materials, preventing pollution, and complying with environmental legislation.
Ccl quality environmental management system issue 05 dated 011113 for webCCL Concrete
This document outlines CCL Quality & Environmental Management System (QEMS). It includes the scope, references, terms and definitions. The policy states the company's commitment to meeting customer needs while minimizing environmental impact. Quality objectives include striving for zero non-compliances and complaints. Environmental objectives involve promoting awareness, reducing waste, and continually improving performance. Management representatives are responsible for ensuring QEMS processes are established and awareness is promoted. The QEMS is based on ISO 9001 and 14001, and involves sales, purchasing, operations, quality and environmental control, with monthly management reviews.
This document compares reinforced concrete and post-tensioned concrete slab options for a high-rise building project in London called Strata SE1 from a sustainability perspective. It finds that using post-tensioned concrete slabs allowed savings of 720 tons of CO2 emissions from slab material alone compared to conventionally reinforced concrete. The post-tensioned option also had shorter construction time, better social impacts during construction and use, and did not have higher costs despite its environmental and social benefits. The study shows that pursuing more sustainable structural design need not compromise other factors like cost or construction schedule.

2. expanding horizons...
CCL is committed to high quality, innovative
engineering solutions and outstanding service.
CCL has been at the forefront of design and
construction for more than 70 years. Our systems
are extensively used in high-calibre structures,
bridges, oil platforms, sports stadia, nuclear
power stations, office and residential buildings
across the world.
CCL Design
The CCL design team has worked on thousands of prestigious structures
around the world. With vast experience and a proven ability to create
innovative solutions, we specialise in the bespoke design of bridge
bearings that allow the creation of cutting-edge, pioneering structures.
CCL Quality
Delivering quality at every stage, all CCL bridge bearings are designed
individually to exacting standards using high specification materials from
approved sources. We use only the latest design software and FEA
analysis and employ bespoke programs to optimise the design for
efficiency and cost. We operate a quality management system that
complies with EN ISO 9001.
CCL Commitment
Committed to providing a first class service across the globe, CCL
has a reputation for hands-on approachability, going further to
deliver a responsive, flexible, cost-effective service and high quality
solutions worldwide.
“ CCL offer a unique, high quality, end-toend service, from initial design through
to manufacture and installation.”

3. Bridge bearings support structures at a constant elevation, carrying forces from the superstructure into the
substructure and allowing necessary superstructure motions to take place. The same principles apply to all types
of structure where forces are exerted. CCL advanced solutions help create innovative bearings that anticipate
and counteract these forces.
Irreversible rotations and translations are due to the effects of concrete shrinkage, settlement, construction,
dead and superimposed dead loads or any similar effects and will occur only once.
Reversible rotations and translations are due to the effects of temperature, wind and live loads and will
occur repeatedly.
DOWNWARD FORCE
Acts vertically through the centre of the bearing.
TRANSVERSE FORCE
LONGITUDINAL FORCE
Forces, rotations and translations act
perpendicular to the bridge main
centre line.
Forces, rotations and translations act
along the bridge main centre line.
UPLIFTING FORCES
Acts vertically upwards due to vibration, design of bridge or the weight of
the superstructure that does not provide significant compressive load.

4. bearing types...
CCL design bespoke bearings to exacting standards. Most structures require a mixture of bearing types
and we advise our clients to contact us at an early stage to ensure we design bearings that perfectly
match the structure requirements. Our bearings are made to order to conform to all relevant local and
international regulations and standards. Any of the mechanical bearings can be converted to uplift type.
In partnership with the client, CCL can design a unique bearing that meets all specifications.
PF FIXED POT BEARING
Resists vertical load and provides restraint in all horizontal directions.
The projecting piston of the top plate is fully retained by the metal pot of the
bottom plate to provide full restraint in the horizontal plane. The deformation
of the elastomeric disc allows multi-directional rotation to take place.
PS FREE SLIDING POT BEARING
Resists vertical load and allows horizontal movements and rotations.
Within the base plate a rocker is fully retained in the pot. This rocker has a
lubricated, dimpled PTFE disc which slides against the stainless steel plate.
The stainless steel plate is fitted to the machined top plate allowing free
horizontal movements between the two sections of the bearing.
PG GUIDED SLIDING POT BEARING
Resists vertical load and provides perpendicular restraint.
In the base plate a rocker is retained in the pot with a lubricated, dimpled PTFE disc to
slide against the stainless steel plate. The stainless steel plate is fitted to the machined
top plate between two guide rails, which resist the horizontal load in one direction.
Horizontal movement occurs along the length of the guide rails. The deformation of the
elastomeric disc under the rocker plate allows multi-directional rotation to take place.
4
5. FP FIXED PIN BEARING
Caters for vertical load but resists horizontal loads in any directions.
Elastrometric bearings would generally be positioned next to the
Fixed Pin Bearing to take up the vertical load.
UG UNIGUIDE BEARING
Does not cater for vertical load but provides undirectional movement and
resistant to the horizontal load in the perpendicular direction.
Elastrometric bearings would generally be positioned next to the
Uniguide Bearing to take up the vertical load.
LR ELASTOMERIC BEARING
Resists vertical load and provides horizontal movements and rotations.
Caters for vertical load where movement is controlled by shear deflection and
rotation is by angular deformation. Steel reinforced plates are vulcanised in
alternating rubber layers which are then enclosed by a rubber outer layer,
increasing the bearing resistance to ageing caused by external influences, in
particular ozone.
PR/SR PLAIN PAD BEARING AND STRIP
Resists low vertical load and allows small movements.
Non-reinforced Elastrometric Pads and Strips are used where low loads and
small movements and rotations are expected. They are the simplest type of
bearing, readily available and easy to install.
BESPOKE SPECIAL BEARINGS
In addition to the standard range of mechanical bearings, CCL design
and manufacture bearings to suit customer requirements; often
recommending types of materials or corrosion protection for highly corrosive
areas such as marine locations, or heavily polluted industrial environments.

6. CCL design...
Continual investment in design and integrated
manufacture means bespoke has become standard
From ideas to installation…
Continual investment in design and integrated manufacture means bespoke has
become standard at CCL. CCL design team members are all experienced design
engineers, highly knowledgeable in practical engineering and industry practice.
Our engineers can adapt their design skills for special projects and specific
national codes. Years of extensive experience mean we understand that
bearings design and supply is critical if a project is to be delivered on time and
to specification. The CCL team draws upon skills from across the Group
delivering bespoke solutions that stand the test of time.
Our Design Philosophy
Each project is unique and we continue to invest in the latest technology,
training and materials to make this a reality. Our design team are from both
structural and mechanical engineering backgrounds, allowing us to combine the
structural design needs of the client with a bearing that can be optimised in
terms of manufacture and cost. We encourage all our clients to involve CCL at
an early stage so we can give guidance on selection of bearings and their
interaction with the rest of the structure.
Our Design Process
CCL will commence initial designs based on the information received from clients
or alternatively from site visits on remedial projects if requested. The extent of
our design depends on the information provided, CCL can give general guidance
to consultants at initial stages based on a small amount of data or be fully
involved in the process at structural design stage. CCL has worked on many
complex projects offering early advice that has assisted in minimising costs
and reducing the projects’ critical path.
“ Each and every CCL bearing we design is unique –
not picked from a predetermined table. Anything
lessthan bespoke design is a compromise.”
6
The bearings listed in this publication are merely a guide. We have always
insisted on optimising design for each project. Our extensive investments in
finite element, 3D Modelling, CAD/CAM and parametrics mean CCL can create full
bearing drawings in a very short timescale.
The Manufacturing Process
CCL is a fully approved ISO facility and we adhere to strict quality procedures.
Once bearings are approved they are transferred to our business system and the
drawing issue hard coded to ensure bearings are produced to the client’s
approved specification.
All components are fully inspected on receipt at CCL and are fully traceable to
source, parts are then machined or assembled to a unique order number for the
specified project. On completion every bearing is fully inspected and tagged
before release to our despatch area.
Testing and Installation
Depending on the client’s wishes and budgets, bearings can either be witness
tested at our test facilities or accredited laboratories. CCL staff will be available
to produce test reports and comment on the testing procedure. CCL through its
own site services company can install bearings or carry out certain remedial
works as requested. At CCL we understand site conditions and are available to
supervise installation by the client or review any remedial actions due to
installation issues.

13. LR elastrometric bearings:
CCL Elastometric Bearings are usually designed and manufactured
to British Standard BS 5400: Part 9 :1983 and if required,
calculations can be prepared to take into account EN1337
Specification and the Department of Transport requirements listed
under their Departmental Standard BD20/92.
CCL standard bearings have chloroprene or natural rubber laminates
in thicknesses of 5, 8 and 11 mm and steel plates in thicknesses of
2, 3 and 4mm. Other thicknesses of rubber laminations and steel
plates can be produced if requested.
In addition to this a Quick Production Test (QPT) is carried out on
every bearing to ensure that the bearings have been correctly
formed and will not delaminate.
Steel Plates
Rubber Laminations
PR/SR plain pad and strip bearing:
This bearing type is the cheapest and quickest to produce but allows
small vertical, rotation and shear displacements by elastic deformation.
They should not be used under heavy and constant shear forces to
prolong the lifespan, as long as their maintenance is sustained
throughout their service life.

D
Thickness of individual rubber laminations in mm
E
Grade and type of rubber
F
Thickness of steel plate in mm (standard size 2, 3 and 4mm)
Note:
The number of plates = the number of laminates + 1
Top and bottom cover thickness = 2.5mm
Side cover thickness = 4.5mm
To calculate the total thickness of the bearing:
T = Top and bottom cover thickness + total thickness
of rubber laminations + total thickness of plates.
14
Example:
- Bearing reference 2520-04-08ENR3
- Number of rubber laminations = 4
- Thickness of laminations = 8mm
- Number of plates = 4+1 = 5
- Thickness of plate = 3mm
T = (2.5 + 2.5) + (4x8) + (5 x 3) = 52
16. Elastrometric bearing installation:
BASE FIXITY:
TOP FIXITY:
A. Cast into recess in concrete with bedding mortar fill
D. Cast into in-situ concrete deck
B. Cast onto bedding mortar and built around the edges
E. Glued to beam soffit *(standard method)
C. Glued onto smooth mortar plinth *(standard method)
TOP & BASE FIXITY:
F. Fixed using auxiliary steel plates *(Extreme cases only)
Please note: Bearing must be fixed on the top and bottom faces if positive fixity is required.
