Analysis of Semi-Continuous Composite Beams with Partial Shear Connection Using 2-D Finite Element Approach

In this study, a two-dimensional finite element model using ANSYS software was proposed to study the behaviour of semi-continuous composite beams allowing for the concept of partial shear connection in both sagging and hogging moment regions. Some comparisons with experimental data available in the literature were reported to validate the efficiency of the proposed model. Using the verified model, a parametric study was carried out to investigate the effects of partial shear connection, along with the effects of reinforcing ratio and the presence of column web stiffeners, on the behaviour of semi-continuous composite beams. Based on the results obtained from the finite element analysis, the concept of partial shear connection in the hogging moment regions can be accepted provided that the shear connectors are sufficiently ductile, in spite of the requirement of full shear connection specified in Eurocode 4 for continuous and semi-continuous composite beams.
