Abstract

The net section capacity of channel sections under tension are affected by shear lag effect. In India the strength of channel sections are evaluated by using the equations available for angle sections. Hence, an attempt has been made to check the validity of these equations for channel sections. For this purpose, guidelines available in various codes of practices and literature are revisited. This paper examines the factors affecting the net section capacity of tension members and the various empirical equations from the literature. Different codal equations related to the net section capacity of channel sections are studied and compared with the corresponding experimental results reported in literature. Effect of the gauge, length of connection and the number of row of bolts are studied.
