Week 2 Challenge

AIM:

Apply the IRC live load and model in STAAD pro and perform the structural analysis.

GIVEN DATA:

⦁ Width of the bridge deck is 7m,

⦁ Span of the bridge is 24m,

⦁ Pier size is 2 m diameter,

⦁ The seismic zone is Zone III,

⦁ Wind speed is 42 km/hr,

⦁ Unit weight of soil is 18 kN/m3

PROCEDURE:

IRC Class A Live load data,

1.To create the nodes and assume the y axis 12m.

2.To selected the beam 1m,2m,2m,2m,1m Z axis side create beam and use translation command same X axis side 8m and add beam.

3.Go to specification section to enter the pier size.

4.To enter the supports.

5.To enter the girder size.

6.To enter the cross-beam size.

7.To create a plate, missing distance is 0.5

8.And then add plate, and thick is 0.3m

9.To using translation repute method 15 steps 0.5m distance x axis side.

10.To select all plates translation repute method 15 steps ,0.5m distance z axis side.

11.Select all beams to using translation method 2 steps 8m distance.

12.Select all plates to using translation method 2 steps 8m distance.

13.Next go to the Loading section, IRC Class A live load data and width of vehicle 1.8m. vehicle definition.

14.Load generated, totally 86 loads generated.

15.Load generation type x=0, y=12m, z=2m.

16.Go to run analysis, got to post processing mode.

17.Type one load displacement.

18.Shear using annotated.

19.Bending moment
