| 摘 要： | 为探讨芯柱式构造柱的抗震性能,对建筑平面、立面布置相同的3种二层砌体(无约束砌体、芯柱式构造柱约束砌体和普通现浇构造柱约束砌体)结构在7,8度罕遇地震下的非线性时程响应进行了分析,对比分析了它们的周期、振型、加速度反应、变形以及墙体塑性应变.分析表明,芯柱式构造柱和普通现浇构造柱约束砌体结构比无约束砌体结构的周期略有减小,振型基本相同;8度罕遇地震下加速度反应明显增大,层间位移反应和墙体塑性应变显著减小;芯柱式构造柱对低层砌体结构位移反应和塑性应变的降低作用与普通现浇构造柱相当,可增强低层砌体结构的抗震性能.

| Abstract: | In order to research the seismic behavior of core-tie-column,non-linear dynamic time-history responses of three types of two-story masonry structures with the same architectural layouts were analyzed.They are a masonry structure without restriction and two masonry structures with four core-tie-columns(CTC) or four cast-in-place tie-columns(CPTC).Their periods,vibration modes,acceleration responses,deformations and plastic strains in walls were contrasted and analyzed.The research results show that the perio... |
