摘要：

This paper deals with finite element modelling of the ultimate load behaviour of double skin composite (DSC) slabs. In a DSC slab, shear connectors in the form of welded studs are used to transfer shear between the outer skin made of steel plates and the concrete core. The current study is based on finite element analysis using ABAQUS. In the experimental programme, carried out by the authors, 12 simply supported DSC slabs were tested to failure under a concentrated load applied at the centre. These test specimens were analysed by the finite element method and the analyses have shown that these slabs displayed a high degree of flexural characteristics, ultimate strength and ductility. Close agreement has been observed between the finite element and experimental results for ultimate loads and load-deflection responses. The finite element model was thus found to be capable of predicting the behaviour of DSC slabs accurately. (C) 2001 Elsevier Science B.V. All rights reserved.
