Week 3 Challenge

Aim: Apply the IRS railway loads and model in Staad pro and perform the structural analysis

Given that:Deck width=26m

Span =25m

Piers Height=10m

Pier Size=2.3m

Distance Between two Piers=

Girder Numbers=8

Assuming Girder Size Section Depth=1.7m

Thickness web=0.5m

Section End Node width=1.7m

Width of Top Flange=1m

Width of bottom flange=1m

Thickness of Botto flange=0.3m

Cross Girders=4 at 6.25m interval along Lognitudinal direction

Creation of Girders and Cross girders:

Creation of 0.5 X 0.5 slab plates

Assigning of Proprties to the Cross girders:

Assigning girders Properties

Assigning thickness to Slab plates

Assigning Supports

Complete Structure Render View

Checks should be done for

1. Multiple Structures
2. Duplicate Nodes, beams, Structures
3. Orphan nodes
4. Warped plates
5. Zero length members
6. Overlapping Collinear members
7. Improperly connected beams

Standard Metro gauge loading details are

1. Width is 1.435m

Load Axle length

170kN

170kn 2.2

170Kn 12.4

170 KN 2.2

Creating Vehicle Definition

No of loads to be generated =(Vehicle length +Span length)/intervals required +1

=(2.2+12.4+2.2+25)/1+1
