Vertical shear behaviour of steel‐concrete composite slabs
The design of short span steel‐concrete composite slabs, or even the spans currently used in building construction but with the longitudinal shear behaviour improved by some type of reinforcement system, usually tends to be governed by the vertical shear resistance. Nevertheless, the design model for vertical shear resistance of composite slabs, according to European standard EN 1994‐1‐1, because it is based on the design model for reinforced concrete slabs predicted in standard EN 1992‐1‐1, does not take the contribution of the steel sheeting into account adequately. In this paper several vertical shear design methodologies are presented and compared. The results of an experimental programme, composed by 4 tests on composite slabs with short spans carried out at the University of Coimbra, are shown and discussed. In order to induce a collapse by vertical shear, the composite slabs tested were provided with a longitudinal shear reinforcement system. The experimental results showed that the design model prescribed by EN 1994‐1‐1 is conservative as it neglects the contribution of the steel sheet resistance to the slab's vertical shear resistance.
