Week 5 Challenge

Objective of this challenge is to understand the concept of designing of plate girders, how to determine the web thickness. Understand the concept of the stiffner required for a given load. Know the different types of stiffners, location of stiffners in plate girder. How to calculate the depth required for a given load for a plate girder.

1. Shear resistance of web problem:

2. Check whether intermediate stiffener required for given load:

3. Check whether intermediate stiffener required for given load:

4. Proportioning problem:

Result: Thus we have understood the concept of designing of plate girder. How to check the thickness of web and depth web which will be sufficient for a given factored load to resist the shear foce and moment, buckling. Understood the concept when stiffners are required,
