Experimental and numerical investigations on steel‐concrete interaction of embedded corrugated web composite members

Abstract

The application of trapezoidal corrugated plate as the web for girders, thanks to a number of favorable features, modernizes the manufacture of steel‐concrete composite and hybrid structures and provides an alternative, competitive structure for small, medium and large span beams. However, the traditional headed stud shear connectors on the top flange can be considered obsolete in many ways. By embedding the corrugated steel web to the concrete slab, other types of connections should be used, and the behavior of these kind of connections are really promising. In fact, the embedded corrugated web itself functions as a shear connector, though other additive connectors should be used. To understand the structural behavior and design of these embedded connectors, the first step is the examination of the embedded web. The focus of the research presented in this paper is on the interaction behavior of embedded trapezoidal corrugated webs with additional mechanical shear connectors. As the first steps of the research comprehensive experimental program was completed in the Structural Laboratory of the Department of Structural Engineering in BME. This paper provides an overview for 8 (test) 12 (FE model) specimens of the push‐out test program with the aim to introduce the structural behavior of embedded corrugated steel web and the influence of structural parameters on the shear resistance and deformation capacity through experimental and numerical investigations.
