【 摘 要 】

The mechanical property of the lightweight composite slabs consisting of ceramsite concrete and thin-walled steel beams was experimentally studied. The test results showed that the composite floors had larger stiffness and better entirety, the relation of load P and vertical displacement of the composite slab specimens had evident nonlinearity, but the deflection Δ varied linearly with load P for the load less than 12kN for all the lightweight composite floor specimens. It was seen that distribution of strains of cross section of main steel beams basically agreed with the plan cross-section assumption.
