Original Abstract

The longitudinal shear is a typical failure mode for composite slabs. The load-bearing capacity in longitudinal shear is determined mainly by mechanical bearing capacity of embossments and friction above the support. It is also influenced by effect of curvature, longitudinal strain in the sheeting and vertical load distribution. The mechanical bearing capacity is determined by shape and dimensions of embossments and their distance from bended edge of sheeting, thickness of the sheeting, material properties etc. Moreover when slip occurs the thin-walled sheeting starts to deform and different stress distribution can change local shear bearing capacity of the interface between steel sheeting and concrete. The complexity of problem caused that nowadays methods in standards prescribe full-scale laboratory bending tests. Small-scale shear tests present a less expensive alternative to bending tests. Several design procedures using small-scale tests results has been derived in last decades. Results of two of these procedures are being compared in this paper. Obtained data from small-scale tests as well as results from bending tests which had been previously performed in our laboratory are being used for numerical analysis and parametric study of shear bearing capacity of the slab.
