Week 1 Challenge

Modeling & Analysis in Staad Pro.

As the bridge span is 12 m, two nodes have been created separated by a 12 m distance.

Now using add beam option in the geometry section, a beam has been modeled.

Then the two end nodes have been assigned with simply supported support.

A section of 2 m x 2m has been assumed and is assigned to the beam modelled previously.

In the loading section, a new load is created.

Then under the load case, using add load command, under the member load option, the UDL option is chosen and load is applied.

For analysis, Perform analysis command is added.

Staad Pro. Analysis Results:

In post-processing mode, the following results have been found.

Bending Moment Diagram:

Maximum Bending moment observed: 2017.8 kN.m

Shear Force Diagram:

Maximum shear force observed: 672.6 kN

Conclusion:

It has been found that the UDL to be applied is 112.1 kN/m and the Maximum

bending moment & shear force encountered in the bridge span are 2017.8 kN.m & 672.6 kN respectively.
