B. web shear flow
C. web bearing
D. web crippling
Please scroll down to see the correct answer and solution guide.
Right Answer is: D
SOLUTION
Web Crippling is just like buckling and it happens in the web of a beam when it is being compressed. It often occurs at the supports of a beam, where the bottom flange is resting on a support, and the top flange is holding up the load, such as on a bridge abutment.
In this case, reaction at a support developed due to high concentrated point load on the beam leads to development of high compressive stresses in the thin web close to the upper flange or lower flange. As a result of this, the thin web may develop a fold at a place close to the flange.
Note:
1. Web crippling result in stress concentration and bearing failure.
2. It is analyzed by considering load dispersion at a slope 1:2.5
