Resistance of Steel-Concrete Composite Ceiling Beams of Multi-Storey Buildings

Resistance of Steel-Concrete Composite Ceiling Beams of Multi-Storey Buildings

Paper in proceedings (conference paper)

The paper deals with the problems of steel-concrete composite structural members, which are applied as the ceiling beams of multi-storey buildings, and composed of steel beam of hot-rolled IPE cross-section, concrete slab and profiled sheets, here having a function of a lost formwork. In the paper the theoretical comparative study of the resistance of the particular selected type of steel-concrete composite ceiling beam, among others in the connection with its deflections is presented. In the study the accent is especially paid to the link between ultimate limit state and serviceability limit state, in parallel together taking into account the beam span, cross-section dimensions (steel beam cross-section, concrete slab cross-section and profiled sheet) and grades of steel and concrete used in the mentioned load-carrying structure. The attention has been paid mainly to the resistance of the beam, subjected to the flexure effects, in relation to the corresponding deflections and in this connection to the evaluation of the reserve in the cross-section capacity, with regard to the economy and efficiency of the structural design. The study has been, among others, inspired by the static and structural design of the real building with steel / steel-concrete load-carrying structure, and evoked by the need of more effective and more economical design because of inappropriate large cross-sections in origin design.
