Review On Parametric Study Of Performance Of Different Types Of Trusses For Pune Railway Bridge Across Bhima River Miss. Chavan Simran Anil1, Prof. Mrs. S. N.

The
primary benefit of structural steel over other structural materials is its strength and ductility. When compared to concrete, it has a greater strength-to-cost ratio in tension and a slightly lower strength-to-cost ratio in compression. Steel has a substantially greater stiffness-to-weight ratio than concrete.
reasonable loads and forces that may occur over its lifespan. In India, a general form of steel bridge is now being developed, albeit the mild steel bridge pattern will need to be elevated over time owing to increased train traffic and short distance routes. A bridge is a structure that carries a road, railway, or other service across a barrier such as a river, valley, or other road or railway line, either without intermediate support or with a limited number of supports at appropriate locations. Steel is frequently employed in the building of bridges of different sizes all around the globe. It is a flexible and efficient substance that offers efficient and long-term solutions. It is suggested in this dissertation to conduct analysis and design of several kinds of trusses for a steel bridge in Pune. The present research entails analysing and designing the truss using STAAD PRO software. A length of 366 m and a width of 7.6 m are taken into account. The number of bays is 30 by 12.2 m, the number of tracks is two, the track gauge is broad gauge, and the track width is 1.676 m. For seismic analysis, seismic zone III is used, and IS 1893 (Part III) 2016 is used. Wind analysis is performed using IS 875 (Part III). For static and dynamic analysis, Warren trusses, Pratt trusses, and Howe trusses are compared. And create the most cost-effective structure for the Bhima River.

1. INTRODUCTION A bridge is an essential structure that is required for a transportation network. Traditional bridges have been replaced with a cost-effective structural system as a result of fast technological advancement. In India, a general form of steel bridge is now being developed, while the mild steel bridge pattern is expected to grow over time owing to increased train traffic and short distance routes. A bridge is a structure that carries a road, railway, or other service across a barrier such as a river, valley, or other road or railway line, either without intermediate support or with a

1.
They could support more weight over greater distances with less material loss, allowing for shallower footings.
2.
If time is of the essence during the building process, steel is a good choice since it may be partially constructed off-site before being assembled in its final location.
3.
Constructing steel bridges in congested metropolitan areas with little room to manoeuvre causes little interruption to local residents and businesses.
4.
Steel bridges last longer in operation than their concrete counterparts.
5.
Steel bridges, because to their shallow profile, are visually pleasing.
6.
When compared to other types of bridges, steel truss spans may save you money.
7.
Steel truss bridges are quick to assemble and save building times.
8.
The architecture of this bridge exemplifies adaptability.
9.
Dynamic loads are no match for the steel bridge's strength.
