Abstract

Whilst there has been extensive research about reduced web section beams; RWS, their behaviour when excited by ground motion and they are overlaid by slabs is yet not well understood. This study fills this knowledge gap by assessing results of a high-definition finite element representation of non-seismically detailed RWS connections with slabs. The effect of the presence of composite action over the web opening is assessed, focusing on effects induced by size and location of the web openings. Simulations show that these connections can reach a 4% interstorey drift, thus allowing them to be part of special moment frames following AISC 341. Moreover, beam, column and joint tearing were avoided entirely, and at the most, brittle failure of bolts in the end plate was observed, a consequence of lack of capacity design.
