【摘要】 基于预应力高性能混凝土梁的低周反复荷载试验,对其破坏形态、滞回曲线、延性、耗能能力、刚度退化、变形恢复能力等抗震性能进行了较为深入的研究。研究结果表明:预应力高性能混凝土梁具有较好的抗震性能。更多还原

【Abstract】 Based on experiments of prestressed highperformance beams under low reversed cyclic loading, failure pattern, hysteresis curves, ductility, energy dissipation, rigidity degeneration and deformationrestoring behaviors, etc. are studied systematically. And studies show prestressed highperformance beams have better seismic performance.更多还原
