Effects of RC floor slab on hysteretic characteristics of steel beams subjected to large cyclic loading
Abstract
The primary objective of this research was to examine the interaction between the steel beam and RC floor slab (composite action). It was found that the steel beam moment capacity for positive bending increased about 1.5 times by the presence of RC floor slab. RC floor slab did not affect the beam moment capacity in negative bending. During small beam rotations of 0.002 to 0.003 rad, however, the beam strength increased 1.2 to 1.4 times even in negative loading. The effective width estimated from slab compressive force approximately equals the column width, which is much smaller than the effective width stipulated by the AIJ composite code.
