Abstract

Welded steel beams with trapezoidal box cross-sections and specially punched webs were developed to be preferably applied together with hollow core pre-stressed concrete slabs as composite beams in slim floors. Heights of standard produced steel beam copy the range of produced HC-units heights. Utilization of these slim composite beams enables to achieve an effective solution also in combination with filigree or in-situ cast concrete decks. The aim of the present investigation is to analyze the behavior of load carrying capacity for slim floor composite beam supported on precast column. This study describes a full-scale test on a typical model beam of 6m span for its flexural behavior with hinged supports and three points loading. The observed strength parameters are compared with predicted failure loads according to international code provisions with the help of Finite Element Analysis programme Delta beam FEM.
