摘要
通过对一榀两跨三层的方钢管混凝土组合框架在低周反复荷载作用下的模型试验,深入研究了方钢管混凝土组合框架的滞回性能、延性、耗能能力和刚度退化等抗震性能。研究结果表明:方钢管混凝土结构的抗震性能优于混凝土结构。
Based on experiment of a piece of concrete-filled rectangular steel tube ( CFRT) frame under low reversed cyclic loading, hysteresis behavior, ductility, energy dissipation and rigidity degeneration are studied systematically. And studies show that the CFRT structure has better seismic performance than the reinforced concrete structure.
