Abstract
The present study aims to obtain fundamental properties of LWA concrete, its stress-strain model under confinement and seismic properties of LWA concrete members. The tests showed LWA concrete has lower tensile strength and modulus of elasticity compared with normal concrete. Under compression LWA concrete members showed brittle failure and little confinement effectiveness of lateral hoops. The complete stress-strain curve was proposed. Cyclic loading test showed that LWA concrete column has almost the same flexural strength and displacement capacity compared with that of normal concrete. Higher energy dissipation and damping ratio found in LWA concrete column. Simulation for load-deformation relationship of LWA concrete column has been done.
