Abstract:
Four steel-concrete composite box-beams(SCCBBs)with different shear connection degrees and height-width ratios of web were experimentally studied under low-cyclic reversed loading. The seismic performances, such as failure mode, hysteretic behavior, skeleton curve, energy-dissipating capacity, ductility, and rigidity degeneration rule, were deeply studied. The influences of shear connection degree and height-width ratio of web on the seismic performance were mainly analyzed. Study result shows that according to different shear connection degrees and height-width ratios of web, there are four types of failure modes, which are local buckling failure, bending-cutting failure, compressing-bending failure, and shear failure. Load-deflection hysteretic curve and skeleton curve can be divided into three stages that are elasticity, elastoplasticity, and failure. Load-deflection hysteretic loops, with different shear connection degrees and height-width ratios of web, are plump and do not have obvious rheostriction, which shows that SCCBB has good seismic performances. Skeleton curve becomes plumper and energy-dissipating capacity becomes higher when shear connection degree increases, but the change of ductility is not obvious. Ductility becomes better and energy-dissipating capacity bocomes higher when the height-width ratio of web increases. The influences of shear connection degree and height-width ratio of web on rigidity degeneration are greater at earlier stage and less at later stage. 3 tabs, 12 figs, 22 refs.
