摘要
中空型钢混凝土柱是一种适于预制装配结构的新型构件.论文应用ABAQUS有限元对9个中空型钢混凝土压弯构件的滞回性能进行了参数分析,讨论了轴压比、配箍率和配钢率三个参数对构件承载力、延性及耗能能力的影响.结果表明,中空型钢混凝土压弯构件具有较好的延性,按现行型钢混凝土规范要求进行设计,基本能满足框架柱的抗震要求.
SRC hollow column is a new type of structural member fitting for prefabricated construction. Employing ABAQUS FEM 9 SRC hollow beam-columns under quasi-static cyclic bending are analyzed considering different parameters such as axial compres- sion ratio, steel ratio and stirrup ratio. The influences of these parameters on the hysteretic behavior of SRC hollow beam-columns are fully discussed. It is shown that SRC hollow beam-columns designed to the current Chinese SRC structural code can basically fulfill the seismic requirements for frame columns.
