FEA validation on the degree of composite action of composite reduced web section (RWS) connections under cyclic loading

Almutairi, F. F. & Tsavdaridis, K. ORCID: 0000-0001-8349-3979 (2023). FEA validation on the degree of composite action of composite reduced web section (RWS) connections under cyclic loading. Paper presented at the The 10th Hellenic National Conference of Steel Structures, 19 Oct 2023, Athens, Greece.


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 loads with positive and negative bending moments. This paper presents detailed FE models capable of simulating the behaviour of the experimental test. Validated models were used for a parametric study, the aim of which is to better understand composite bolted RWS connections with demountable bolted shear studs under cyclic loadings. Based on the results, it is apparent that the composite RWS connections can also be employed, alike bare steel RWS connections, to improve the seismic performance of steel structures engaging the strong column – weak beam approach, despite the type of shear studs and the local strengthening in the vicinity of the web opening due to the concrete slab, which is the opposite of the web reduction locally.
