Hysteretic Performance

Overall 12 specimens were experimentally investigated in this paper to study the hysteretic behaviors of the concrete-filled square CFRP-steel tubular (S-CFRP-CFST) beam-columns. The test results indicated that CFRP can provide transverse confinement effect and longitudinal strengthening effect for the concrete filled square steel tubular (S-CFST) beam-columns effectively and the local buckling of the steel tube is deferred. The hysteretic load-deflection curves and the hysteretic moment-curvature curves at the mid-span of all the specimens are generally plump, and it shows these specimens have good hysteretic performance. In the later loading period, the load bearing capacity drops.

Seismic Behaviors

According to the poorly seismic behaviors of composite staggered trusses system, an improved composite staggered trusses system was proposed. Based on the experimental study of a 1/3 scale improved composite staggered truss frame steel structure model under cyclic loading, the seismic behaviors and failure mechanism was studied, and the seismic behaviors was evaluated by the hysteretic behavior, ductility, energy dissipation and rigidity degeneration. The study showed that the improved composite staggered truss steel structures had the advantages in bearing capacity, ductility, deformability and energy dissipation, but the lateral rigidity was weak and non-uniform along its vertical layout. The stress measurement showed that the plastic hinge formed in the web members of the truss firstly, then, in the chord members of the truss, and finally the plastic hinges formed in the column, earthquake energy mostly dissipated by the truss members, the failure mechanism of the improved composite staggered truss steel structures was the beam hinges failure mechanism.
