| 摘 要： | 对普通钢-混凝土组合梁的钢梁和混凝土板施加预应力,即形成了预应力钢-混凝土组合梁.基于5根梁的低周反复荷载试验,对预应力钢-混凝土组合梁的破坏形态、滞回曲线、变形恢复能力、延性、耗能能力、刚度退化等抗震性能进行了较为系统的研究,重点探讨了预应力度和剪力连接程度对其抗震性能的影响.研究表明,预应力钢-混凝土组合梁具有良好的抗震性能.

| Abstract: | Prestressed steel-concrete composite(PSC) beams are formed by stretching the tendons in steel beams and concrete slabs in ordinary steel-concrete composite beams.Based on experiments of five beams under low reversed cyclic loading,failure pattern,hysteresis curves,deformation-restoring behaviors,ductility,energy dissipation and rigidity degeneration of PSC beams are systematically studied.The influence of PPR and degree of shear connection on seismic performance of beams is emphasized.Studies show that PSC ... |
