The effective length of double angles strut with angles placed back to back on each side of gusset plate is

if ISHB is used as a column , what is the limiting d / tw ratio ?

For a single angle strut , if b/ tf ratio is 10.2 , the flange is classified as

As per IS :800 , effective length of column hinged at both ends

As per IS :800 , effective length of column fixed at both ends

Cross section which can develop plastic hinges and have the rotation capacity required for failure is called

Cross section which can develop plastic moment of resistance , but have inadequate plastic hinge rotation capacity because of local buckling is called

Cross Section in which the extreme fibre in compression can reach yield stress , but can not develop the plastic moment of resistance due to local buckling is called

Cross sections in which are elements buckle locally even before reaching yield stress is called
