Consider the following statements:
I. Effective length of a battened column is usually increased to account for the additional load on battens due to the lateral expansion of columns.
II. As per IS: 800-1984, permissible stress in bending compression depends on both Euler buckling stress and the yield stress of steel.
III. As per IS: 800-1984, the effective length of a column effectively held in position at both ends but not restrained against rotation, is taken to be greater than that in the ideal end conditions.
The TRUE statements are
