MECHANICAL BEHAVIOR OF STEEL REINFORCED CONCRETE L-SHAPED COLUMN UNDER LOW CYCLIC REVERSED LOADING
In order to reveal the mechanical behavior of steel reinforced concrete (SRC) L-shaped column, 8 specimens were designed, in which 4 specimens were finished by cantilever column loading device, and another 4 specimens were finished by parallel crosshead equipment. The failure patterns, bearing capacity, hysteretic curves were obtained from the test. The experimental study indicates that SRC Lshaped columns major failure patterns are shear compression failure, shear-bending failure and flexural failure. It has strong bearing capacity and excellent seismic behavior. Specimens hysteretic performances are related to test device. When specimen finished by cantilever column loading device, its hysteretic curve is asymmetric, but, when specimen finished by parallel crosshead equipment, its hysteretic curve is symmetry. In actual project, SRC L-shaped column is restrained by floor, its hysteretic curve is symmetrical.
