Experimental Study of Mechanical Behavior of Fabricated Slabs of H-type Thin-walled Steel Beams and Lightweight Concrete

Abstract

Through the static loading test of 3 fabricated slabs consisting of H-type thinwalled steel beams and lightweight aggregate concrete, the mechanical property and deformation behavior of the slabs was studied. The results showed that the composite slabs had better entirety and deformation ability. It was shown that strengthening the restraint at the ends of the main beam can improve the bearing capacity of the slabs in a little degree. Increasing the height of the secondary beam can increase the ultimate bearing capacity of the slabs, but it has little influence on the integral stiffness of the composite slabs presented here.
