stiffness of anti-roll bar. Further these parameters are also affecting the body roll angle. By the
optimization of these geometric parameters we can able to increase the stiffness of bar and which will
help to reduce the body roll angle. To calculate the stiffness of anti-roll bar Finite Element software

literature survey, however they haven’t taken all the suspension characteristics in the calculation of
moment caused by the suspended and non-suspended masses. The equilibrium condition is considered
between the moments of the force acting on the suspended and non-suspended masses and moments of
reaction of the springs and anti-roll bar used in suspensions. The comparison of different anti-roll bar is
based on the basis of stiffness per weight. The anti-roll bar which having more ratio of stiffness per
weight can be used in the vehicle. As it will improve the stiffness of bar with small increase in weight,
which will result in the improving roll stability of the vehicle.

This document summarizes an experimental study that compared the behavior of steel beams with trapezoidal corrugated webs with different corrugation angles (25°, 30°, 35°, 45°, 60°) under point load conditions. Five steel beam specimens were fabricated and tested.

This document summarizes an experimental investigation on reinforcing concrete columns with fiber-reinforced polymer (FRP) jacketing. Circular reinforced concrete columns with both solid and hollow cross-sections were tested under axial compression loads. The columns were either conventionally reinforced or confined with external FRP wrapping. Test results showed that FRP-confined hollow columns exhibited a 35% increase in ultimate load capacity compared to unconfined hollow columns. FRP jacketing also improved ductility by reducing axial and lateral deformations at high loads. The study demonstrates that FRP confinement enhances the strength and deformation capacity of hollow reinforced concrete columns.

The results showed that the beam with a 35° corrugation angle experienced 21-82% less central deflection and 31-104% less lateral displacement compared to the other beams, indicating it provided the optimal combination of strength and material efficiency. Therefore, a trapezoidal corrugated web with a 35° corrugation angle can result in improved structural behavior for steel beams.
IRJET- Kinematic Design Methodology of Vertical Coil TongIRJET Journal
- The document presents a design methodology for calculating gripping forces and joint forces in a vertical coil tong (VCT) used for lifting steel coils.
- Static force-moment equilibrium equations are used to calculate the gripping force (2.76 times the load lifted) and forces in joints of a 5-ton VCT modelled in CATIA V5 lifting coils of 900mm and 1300mm diameter.
- Structural analysis in ANSYS shows von-Mises stresses in the VCT are within material yield strengths for self-weight, and when holding coils. Weight reduction of 4.81% is achieved by optimizing the thickness of the highest stressed J-link from 75mm to 50mm.

IRJET- Experimental Investigation on RCC Long Hollow Circular Columns with FR...IRJET Journal
This document summarizes an experimental investigation on reinforcing concrete columns with fiber-reinforced polymer (FRP) jacketing. Circular reinforced concrete columns with both solid and hollow cross-sections were tested under axial compression loads. The columns were either conventionally reinforced or confined with external FRP wrapping. Test results showed that FRP-confined hollow columns exhibited a 35% increase in ultimate load capacity compared to unconfined hollow columns. FRP jacketing also improved ductility by reducing axial and lateral deformations at high loads. The study demonstrates that FRP confinement enhances the strength and deformation capacity of hollow reinforced concrete columns.

This study compares the seismic performance of circular and rectangular reinforced concrete columns under monotonic and cyclic loading through experimental testing and finite element analysis. Experimental tests showed that circular and equivalent rectangular columns had similar load-deflection behavior and achieved similar strength and ductility under flexural and shear dominated failure modes. Finite element analysis of 20-story buildings with circular and rectangular columns found that the building with circular columns experienced 25% greater lateral displacement but similar drift, base shear, overturning moment, and time period compared to the rectangular column building. Reinforcement requirements were up to 50% higher for circular columns compared to rectangular columns under both monotonic and cyclic loading conditions. In conclusion, both column shapes performed similarly but rectangular columns were found to be more econom

This document analyzes and compares the design of a 15-story reinforced concrete structure with an H-shape in different seismic zones of India. Two models are considered - one with connecting beams between the wings of the H-shape and one without. Both models are modeled and analyzed in STAAD Pro software. The results, including shear forces, bending moments, deflections, and steel reinforcement percentages, are compared for the two models across zones II through V. The analysis shows marginal differences between the two models, with the model without connecting beams performing slightly worse in some parameters. The document concludes that connecting beams have little impact on the structural behavior but can improve construction.

Abstract— The present work envisages a comparative
study between various gantry girder profiles. The design is
performed considering both strength and serviceability
criteria as per IS 800:2007. The analysis for dead load and
live load are done as per IS: 875 -1987 (Part-I) and IS: 875

profile geometry that are chosen includes ‘I’-section with top
and bottom plates, symmetrical plate girder section,
‘I’-section with ‘C’-section as top flange, plate girder with
top flange as rolled ‘C’-section and unsymmetrical plate
girder section. The problems are formulated taking in to
consideration of practical demands of industries. Gantry
girders are analyzed for gantry spans of 5m, 7m, 9m and 12m
each with crane capacity of 100kN, 200kN and 300kN
respectively. An attempt is made to identify the most
optimum combinations of sections for each category of crane
capacity and gantry span. Finally, to aid designers, handouts
in the form of graphs, charts and tables are furnished which
can be used to identify the best possible option of gantry

I. INTRODUCTION
Gantry cranes have major priority in heavy industries,
manufacturing plants, shipping docks and railway yards
where transportation of excessive weights occurs routinely.
Gantry girder is the segment which transfers the loads from
the crane to the vertical load bearing members.
Gantry girders are designed in a very conservative
approach for the maximum factored vertical and lateral
bending moment and share forces. So the capacity of the
section can be increased by optimization of the gantry profile
and at the same time, the requirement of steel can also be
reduced.
In this paper, analysis and design of gantry girder is
performed by using different gantry profiles which are
represented in Fig.1.

for this study. The various other specifications that are taken
as constant for all the cases are mentioned in Table I.

Minimum hook approach 1.2m
Wheel base distance 3.5m

Self-weight of rail section 0.3 kN/m
Self-weight of gantry girder section 1.6 kN/m
Diameter of crane wheel 150mm
Grade of steel used E250
Design procedure:
Step1: Calculation of maximum wheel load
• For calculating maximum wheel load the hook of the
trolley should be at a distance of minimum hook approach
from the end of the crane girder.
• Due to impact loading 25% extra load should be
considered (as per IS 875(2):1987 clause 6.3) [7].
• A load factor of 1.5 should be multiplied with the obtained
value [6].
Step2: Calculation of surge load
• Total lateral surge load should be considered as 10% of the
crane load plus trolley load.
• A load factor of 1.5 should be multiplied with the obtained
value.
Step3: Calculation of longitudinal breaking load
• Longitudinal breaking load should be calculated as 5% of
the static wheel load.
• A load factor of 1.5 should be multiplied with the obtained
value.
Step4: Calculation of bending moment
• Bending moment due to wheel load should be calculated
using absolute maximum bending moment theorem.
• Bending moment produced by self-weight of gantry girder
and rail section and bending moment due to longitudinal
breaking load should be considered.
• Summation of all these bending moments is the total
bending moment generated in the gantry girder. A load factor
of 1.5 should be multiplied with the obtained bending
moment to find out the factored bending moment.
• Bending moment due to lateral surge load should take into
consideration which acts in the horizontal direction.
Step5: Calculation of shear force
• Maximum shear force due to wheel load can be obtained
when one set of crane wheel is placed just at the support.
• Shear force due to self-weight of gantry girder and rail
section and reaction due to drag should be considered.
• Summation of these entire shear forces is the total shear
force generated in the gantry girder. A load factor of 1.5
should be multiplied with the obtained shear force to find out
the factored shear force.
Step6: Assumption of section
• The assumed depth of the gantry girder section should be
within the economic depth and the shear depth.
• Area of flanges should be calculated from the bending
moment criteria. As the gantry girder has to withstand
bi-axial bending so the assumed area of flanges should be
increased by 30-40%.
Step7: Check for bending moment capacity of the section
• Vertical and lateral bending moment capacities of the
provided section should be calculated as per IS 800:2007
clause 8.2.2. [5].
• If the interaction ratio for bi-axial bending is less than one
then the section is safe against bending.
Step8: Check for share force capacity of the section
• Shear force corresponding to web buckling Vcr is
calculated as per clause 8.4.2.2 of IS 800:2007 [5].
• If the calculated share force capacity of the section is
greater than the factored share force then the section is safe
against share.
Step9: Check for web buckling
• Buckling strength of unstiffened web Fcdw can be
calculated as per clause 8.7.3.1 of IS 800:2007 [1] [5].
Step10: Check for web crippling
• Local design capacity of web in bearing Fw can be
calculated as per clause 8.7.4 of IS 800:2007 [5].
Step11: Check for deflection
• Lateral and horizontal deflection of gantry girder under
service loads should be less than (gantry span/750) in mm [4].
III. RESULTS AND DISCUSSION
The generated factored vertical bending moments (MZZ),
lateral bending moments (MYY) and factored shear forces
(SF) of different gantry spans are tabulated in Table 2. These
entities are load dependent entities and remain constant for all
types of gantry profiles.

IV. DESIGN METHODOLOGY
The design is initiated with a very basic symmetrical sections
like “rolled I-section with top and bottom plates” and
“symmetrical plate girder section” [2] [3]. But the problem
with the first gantry profile is the depth of the rolled section is
limited so for higher gantry spans and crane capacities the
available profile becomes very uneconomical.
For gantry girders as the horizontal surge load is transferred
at the top flange level (specifically at the contact point of
crane wheel and gantry rail) so using unsymmetrical section
with bigger compression flange is found to be more
economical. So in the subsequent trial the gantry profiles are
considered as “rolled I-section with rolled C-section as top
flange” and “web and bottom flange as plate section with top
flange as rolled C-section”. As a result the sections are found
to be very economical but the problem is the rolled sections
are not available for the higher gantry spans and crane
capacities.
To eliminate this problem in the third and final trial keeping
the same geometry as per second trial the whole gantry
profile is designed as plate girder section with bigger
compression flange as C-section. This results into the most
economic section for gantry span of 9m and 12m.
V. CONCLUSIONS
• Load calculations for gantry girders are done in a
very conservative way so by optimizing the gantry
girder profile economy can be achieved.
• Gantry girders are such kind of steel beams where
vertical and lateral bending moments can come at a
same time. So the designed sections need to be safe
against bi-axial bending.
• For gantry girders horizontal loads are released at
the top flange level so unsymmetrical sections (with
a bigger compression flange) will be more
economical than symmetrical sections.
