A gap in current design approaches demands explicitly introducing a capacity design approach when designing steel-concrete composite reduced web section (RWS) connections. This paper addresses this gap by presenting detailed finite element models and parametric investigations, focusing on parameters, the presence and absence of composite action ove...

Brittle tearing failure is one of the most dangerous failure modes in moment-resistant connections. Hence there has been successful research in developing fuse strategies that cluster deformation demand away from the column face, well within the beam. However, this approach involves the extensive intervention of the column and provision of stocky s...

Based on the observations from previous earthquakes, brittle failure poses a significant threat to the integrity of steel-concrete composite moment-resisting frames (MRFs). Hence, there has been successful research in developing fuse strategies that cluster deformation demand away from the column face well within the beam. However, this approach in...

This paper presents an experimental study of demountable steel-concrete composite reduced web section (RWS) connections for use in seismic areas. Four composite connection specimens were subjected to sagging and hogging moments to investigate the performance of RWS connections under reversible actions. For such purpose, a single web opening was cre...

This study is part of a large research campaign that studies experimentally and numerically the effect of the degree of composite action to the performance of the extended end-plate RWS connections. The experimental tests involve full-scale testing of three composite connection specimens using demountable bolted shear studs subjected to cyclic load...

Little attention has been paid to reduced web section (RWS) connections with composite slabs under cyclic loading. RWS connections have been proven to act as ductile fuses with a most promising and straightforward choice that requires only one perforation within a beam web without removing the concrete slab. Thus, it could be an economic benefit in...

Whilst there has been research about reduced web section beams; RWS, their seismic behaviour when they are overlaid by slabs is not well understood. This study addresses this by assessing a high-definition finite element repre-sentation of non-seismically detailed RWS connections with slabs. The com-posite action is investigated, focusing on effect...

Concerns have been raised over the presence of concrete slab and resulting composite action in jeopardising the concept of strong column and weak beam seismic design. This comprehensive finite element analysis (FEA) aims to study the effect of the degree of composite action and other two parameters; namely, size and location of the web opening, on...

Due to the concerns regarding the effects of the composite action on the seismic performance of beam‐to‐column connections leading to premature brittle fracture of the beam bottom flange, this paper introduces a comprehensive finite element (FE) analysis studying the effect of the degree of composite action to the performance of the bolted extended...
