Experimental study of mechanical properties of lightweight composite floors

Abstract

The mechanical performance of the fabricated composite floors consisting of thin-walled steel beams and lightweight aggregate concrete was experimentally studied and effect of some important factors on the mechanical properties of the composite floor specimens was discussed. The experimental results showed that the composite floors had better plastic deformation capacity, greater bearing capacity and better entirety, and effect of the geometrical construction of cross section of the main steel beams on the mechanical property of the floors was related with deformation of the floors in a degree.
