Week 3 Challenge

Given Data-

Type of Bridge =I-section Girder bridge

Span of the bridge =25 m

Centre-to-centre distance between two piers along the width of the bridge deck = 26 m,

Height of Pier = 10m

Task-

To Apply the IRS railway loads and model in Staad Pro and perform the structural analysis.

Solution:

From the observation from the drawing, it is concluded that this bridge carries a four-lane road with a footpath 1.8 m wide, central shoulders 1.8 m wide, and outer shoulders 3.00 m wide.

Number of Bearings = 8

Number of Girders = 8

For the sake of analysis, a line diagram has been drawn on STAAD Pro and four columns and relevant lateral and longitudinal beams are assigned.

IRS loading for Broad gauge has been assigned to the structure and the structure is thus analyzed.

An .STD file has been attached.
