OPTIMIZATION OF PRESTRESSED CONCRETE BEAMS-student vincenzo robertiVincenzo Roberti
This document summarizes a student's final report on optimizing the design of prestressed concrete beams. The student formulated the problem using nonlinear programming to minimize the cost of the beam based on design variables like section dimensions and amount of prestressing steel. Constraints included practical bounds on dimensions and strength requirements. Standard and idealized beam sections were analyzed. Results found that a double tee section minimized cost and increasing concrete strength reduced cost for T-beams with 7 ksi concrete being optimal. Standard sections analysis confirmed idealized section results. The student concluded the idealized section optimization provided effective guidance to find the lowest cost standard beam section design.

Gantry girder
Gantry girder or crane girder hand operated or electrically operated overhead cranes in industrial building such as factories, workshops, steel works, etc. to lift heavy materials, equipment etc. and carry them from one location to other , within the building
The GANTRY GIRDER spans between brackets attached to columns, which may either be of steel or reinforced concrete. Thus the span of gantry girder is equal to centre to centre spacing of columns. The rails are mounted on gantry girders.
Loads acting on gantry girder
Gantry girder, having no lateral support in its length (laterally unsupported) has to withstand the following loads:
1. Vertical loads from crane :
Self weight of crane girder
Hook load
Weight of crab (trolley)
2. Impact load from crane :
As the load is lifted using the crane hook and moved from one place to another, and released at the required place, an impact is felt on the gantry girder.
3. Longitudinal horizontal force (Drag force) :
This is caused due to the starting and stopping of the crane girder moving over the crane rails, as the crane girder moves longitudinally, i.e. in the direction of gantry girder.
This force is also known as braking force, or drag force.
This force is taken equal to 5% of the static wheel loads for EOT or hand operated cranes.
4. Lateral load (Surge load) :
Lateral forces are caused due to sudden starting or stopping of the crab when moving over the crane girder.
Lateral forces are also caused when the crane is dragging weights across the' floor of the shop.
Types of gantry girders
Depending upon the span and crane capacity, there can be many forms of gantry girders. Some commonly used forms are shows in fig .
Rolled steel beams with or without plates, channels or angles are normally used for spans up to 8m and for cranes up to 50kN capacity.
Plate girder are suitable up to span 6 to 10 m.
Plate girder with channels, angles, etc. can be used for spans more than 10m
Box girder are used foe spans more than 12m.

Footings transfer structural loads from a building to the ground. This document discusses various types of footings and their design procedures. Spread footings are the most common type and are proportioned to have an area large enough that soil and building settlement will be minimized. The general design process involves checking that factored loads are less than the soil's allowable bearing capacity and footing thickness is sufficient to resist punching and beam shear. Reinforcement is calculated and placed to resist bending stresses. Combined and strap footings are also discussed along with their unique design considerations. Brick footings can be used for small residential loads.
IRJET- Analysis of Long Span Suspension Bridge under Wind Load and Moving LoadIRJET Journal
This document analyzes long span suspension bridges under wind and moving loads using SAP2000 software. Three bridge models were created with spans of 400m, 500m, and 600m. The bridges were analyzed for wind loads based on Indian and ASCE codes. Moving load analysis used Class AA tracked loads. Results showed time period and deck deflection increased with span while frequency decreased. Suspender forces were lower than sag cable forces. Maximum pylon displacement occurred in the 600m span bridge under wind loads. In conclusion, suspension bridge behavior depends strongly on span length, and wind loads govern perpendicular to the bridge direction.

Parametric study of light gauge steel lipped channel column sectioneSAT Journals
Abstract Light gauge steel lipped channel sections are being used popularly in shops, factories, automobile engineering and industries on account of their high strength to width ratio, simplicity in construction, flexibility in fabrication and high structural efficiency. A lot of research work has been carried out to study the structural behavior of axially loaded light gauge steel lipped column sections considering different parameters. However, structural behavior of light gauge steel lipped channel sections under eccentric loading has not received much attention. The present paper focuses on the experimental study of structural behavior of light gauge steel lipped channel sections under eccentric loading by varying loading position in between center of gravity and shear center of channel column section. Finite element analysis of the section is also done using Abaqus software for different positions of the load. The results indicate that, load carrying capacity of the section increases as the loading position shifts towards supported edge of the section. The failure of the section occurs in the form of local-distortional buckling approximately between 1/3rd - ½ of the height of column. Results obtained by software are found to be in good agreement with experimental results. Keywords – Light Gauge Lipped Channel Column, Structural Behavior, Local Buckling, Finite Element Analysis, Abaqus etc

This document summarizes a thesis analyzing the static and dynamic finite element analysis of a composite leaf spring. The thesis examines a fiberglass-epoxy composite leaf spring used in a Chevrolet vehicle and explores its performance under heavier loads. Analytical calculations and FEA simulations are used to analyze stresses in the leaf spring and identify failures from increased loading. The results suggest reducing leaf spring thickness to lower delamination stresses at the mid-section from dynamic loading. Experimental validation and further studies of hybrid composites and eye-end design are recommended for future work.
Analysis of Non Conventional Cross Section of Pipe Made Of Composite MaterialIJMER
Our search for oil is sending us deep into the sea, however this has its own challenges. The salinity of
the sea, acts as an active corrosive agent, and it steadily weakens the structure to get around this, non-corrosive
composite piping has been deployed in critical regions of the structure. However to enable pipe stacking,
sometimes to avail of space constraints, instead of circular c/s, the pipes are increasingly being made of triangular or rectangular c/s. For such c/s theoretical calculations are not possible, hence we need FEA to help us understand the behavior of such c/s.
Effect of Factors Influencing of Shear Resistance on the Energy Dissipation C...IRJET Journal
The document describes an experimental study on the effect of stirrup spacing on the energy dissipation capacity of reinforced concrete beams under cyclic loading. Three reinforced concrete beam specimens were tested with varying stirrup spacings of 50mm, 75mm, and 100mm. The results found that the specimen with the closest stirrup spacing of 50mm had the highest initial stiffness and dissipated the most energy compared to the other specimens with wider stirrup spacings.
This document contains a summary of a refresher course covering various structural analysis problems. It includes 5 situations involving calculating reactions, tensions, stresses, and shear forces for different structures. The document tests understanding through multiple choice questions after explaining the concepts and showing the calculations for each situation. The situations involve analyzing forces on a portable seat, cables supporting a ceiling, stresses on an element using Mohr's circle, forces on a bridge girder under loading, and stresses in a hollow circular signage pole.

This document analyzes the behavior of steel arch bridge structures with varying rise ratios and deck positions. It models bridges in SAP2000 with rise ratios of L/3, L/4, L/5, and L/6 and analyzes bending moment, deflection, weight, and cable height. Bending moment and deflection increase as rise decreases. The L/6 model exceeds the deflection limit. Deck position also affects deflection and weight, with through-type bridges having the highest deflection and lowest weight, and deck bridges the lowest deflection and highest weight. Analysis of different configurations helps optimize the design for stability and efficiency.
Comparative study of behaviour of cold formed steeland hot rolled steel secti...eSAT Journals
Abstract Cold-formed steel is used in large number of products. For example in metal building construction, for wall coverings, floor decking etc. Cold-formed steel is a basic component in construction of lightweight prefabricated structures like stud frame panels, trusses and portal frames.The Cold formed steel term itself make it different from hot rolled steel due to difference in manufacturing methods. Typically columns, beams and angles etc. are different globally. At room temperature cold formed steel members are formed by bending flat sheets. Cold formed steel sections mainly created using two methods those are break press through and rolling. Where hot rolled steel members are precasted. Therefore cold formed steel sections can be easily available at any place where hot rolled sections are not available. The cold formed steel components can be used for larger and complex structures. The Comparison of cold formed steel section and Hot rolled steel section of equal cross sectional area is done in this research paper. Sections were experimentally tested under axial compression in universal testing machine. Simultaneously, ultimate compressive strength of cold formed members and hot rolled members has been investigated. Also, different properties of the sections such as stresses induced in the sections, strain in the section, axial deflection, and lateral deflection are obtained experimentally. For measuring strain experimentally strain gage foils were used. The validation of results is done by preparing finite element model in ABAQUS software. From experimental work it is observed that cold formed steel sections has more load carrying capacity as compared to hot rolled steel section. Keywords: Ultimate compressive strength, buckling, cold formed steel, deflection, stress, strain, ABAQUS
Analysis of Rc Framed High Rise Structural System with Ground and Intermediat...IRJET Journal
This document analyzes the structural performance of reinforced concrete framed high-rise buildings under wind loads. Four building models are considered: a baseline model, a model with an open 13th floor (soft story), a model with shear walls at the 13th floor, and a bare frame model. The models are analyzed using ETABS software to determine storey displacements and drifts. Results show the soft story model has the highest displacements, while the shear wall model reduces displacements at the 13th floor by around 9% compared to the other models. Storey drift is also highest in the soft story model. In conclusion, the analysis demonstrates how a soft story or shear walls can influence a building's response to wind loads.
This report provides estimates for the size, design, and cost of a gantry crane to lower detector components for the proposed Future Circular Collider (FCC) project. The detectors could weigh up to 6,000 tonnes and need to be lowered 200-400 meters underground. Information is given on the dimensions and design of the existing CMS gantry crane, which lowered a 2,000 tonne detector. Preliminary calculations are shown for the design of the main beam for the FCC gantry crane, assuming dimensions similar to CMS. The calculations check that the proposed steel I-beam cross section meets bending, buckling, and shear requirements to support a 6,000 tonne load at the ultimate and service

Rail transport is one of the important modes of transport in India. Now a days we
see that there are railways that are present for the long as well as short distance
travelling which makes the life of the people easier. When compared to other
means of transport, a railway is the cheapest means of transport. The maintenance
of the railway database also plays a major role in the smooth running of this
system. The Online Train Ticket Management System will help in reserving the
tickets of the railways to travel from a particular source to the destination.

Sri Guru Hargobind Ji - Bandi Chor Guru.pdfBalvir Singh
Sri Guru Hargobind Ji (19 June 1595 - 3 March 1644) is revered as the Sixth Nanak.
• On 25 May 1606 Guru Arjan nominated his son Sri Hargobind Ji as his successor. Shortly
afterwards, Guru Arjan was arrested, tortured and killed by order of the Mogul Emperor
Jahangir.
• Guru Hargobind's succession ceremony took place on 24 June 1606. He was barely
eleven years old when he became 6th Guru.
• As ordered by Guru Arjan Dev Ji, he put on two swords, one indicated his spiritual
authority (PIRI) and the other, his temporal authority (MIRI). He thus for the first time
initiated military tradition in the Sikh faith to resist religious persecution, protect
people’s freedom and independence to practice religion by choice. He transformed
Sikhs to be Saints and Soldier.
• He had a long tenure as Guru, lasting 37 years, 9 months and 3 days
