The present paper reviews the fundamental structural response characteristics and technological issues of composite steel and concrete systems. It assesses the pros and cons of composite structural systems and investigates the efficacy of beam-column members. Design rules for composite constructions are presented and discussed in details in order to get deep insight into their background. Areas of further research are

In composite construction, the floor slabs are cast on permanent steel formwork, which acts first as a working platform and then as bottom reinforcement for the slab. The slabs are supported on the composite steel beams. Also the columns are made either by steel or encased steel member inside the concrete, which acts as a composite member. However, incorporation of many aspects of concrete-steel behavior such as nonlinear multi axial stress-strain response, dilatancy phenomenon, cracking, stain softening, and stress transfer mechanisms between steel and concrete leads to complicated and highly nonlinear behavior. Simplifying assumptions for the interaction between the concrete slab and the steel beam has helped to establish composite construction as an easy to handle extension of the bare steel construction. This paper outlines some recent trends in the analysis and design of composite structures followed by the work carried out by the authors.
