Light weight concrete- on- steel composite beams

Abstract

Six composite beams, five companion pushout specimens, and the necessary control specimens were tested. The major variables were the type of lightweight concrete, the type of loading (short term or sustained), and the degree of shear connection. The results were evaluated and compared with a previously developed theoretical analysis. The theoretical analysis was used to study the effects of partial shear connection, modular ratio, and unshored construction on the behavior of composite beams.
