The following are the statements about tension field method of finding shear buckling resistance of plate girded: which one of them is correct statement?
It may be used if end and intermediate vertical stiffeners are provided.
As the web begins to buckle, it loses the ability to resist diagonal compression.
It gives higher value of shear buckling strength of web compared to simple post-critical method.
