Week 3 Challenge
AIM:
To design a I girder bridge, Apply the IRS Railway loads and model STAAD pro and perform the structural analysis.
GIVEN DATA:
- Width of the bridge deck is 28m
- Span of the bridge is 25m
- Pier height is 10m
PROCEDURE:
1.To create a node x=0, y=0, z=0
2.selected the node copy and paste in z direction 28m
3.selected the z direction two nodes copy past in x direction 25m.
4.To join the nodes in add beam commend.
5.To selected the x axis beam and using translation repute method 4m distance in 7 steps.
6.To selected all the x axis beam and then go to specification>prismatic>Taper.
7.To selected the z axis beam size is (1.20*1.80)m
8.The plan is cantilever beam so create a piers .
9.The pier size is 2.3m diameter
- The pier is fixed support .
11.To use the translational repute method in x axis side 25m distance one step.
12.To selected the two-pier z axis side 20m distance
13.Go to node cursor, 0.5m distance x,z axis
14.Selected the nodes.
15.Add plate and x axis side 49 step translation repute method.
16.Select all plates translation repute method 55 steps z axis side. Plate thick is 0.45m.
- 3D rendering view.
18.Next go to the loading section, vehicle definition IRS Railway loading. Width 1.8m.
19.No of steps 50.
20.Next go to load cases details > load generate
21.Next go to run analysis > go to post process
22.This is deflection
- shear FY
24.Bending moment MZ
25.Beam results
- Maximum shear SY
- Maximum bending moment MY
