| Abstract: | In this paper, the results of experiment on 5 steel-composite continuous beams which have different synthesis force ratio under lowreversed cyclic loading are introduced, and the seismic behaviors which involve failure pattern, hysteresis curves, skeleton curves, rigidity degeneration, energy dissipation and deformation-restoring behavior are analyzed. And the results show that the synthesis force ratio has great influence on the seismic behavior of composite continuous beams. |
