ABSTRACT
This paper aims to study the seismic performance of moment-resisting frames consisting of steel-concrete composite beams subjected to reversed cyclic displacement. The failure patterns, failure mechanism, hysteretic model, deformation-restoring behavior, displacement ductility and energy dissipation capacity of the composite frames are discussed. Hinge is first formed at the composite beam ends. Failure of the two frames under low cyclic displacement reversals is finally governed by crushing and spalling of concrete at top and bottom of columns. Studies also show that the composite frames behave in a ductile manner, and the seismic performance of the composite frames can be significantly improved by the steel-concrete composite beams. In addition, a modified program is employed for full-range analysis of the composite frames.
