摘　　要：面对地震灾害等难题,新型高层装配式蜂窝型钢网格盒式双筒结构体系可以有效应对.采用反应谱和动力时程分析方法,重点分析了多、罕遇地震作用下新型结构在隔震和非隔震情形时的楼层剪力、楼层位移以及抗风验算等指标,并与普通结构进行对比.研究结果表明:非隔震时,新型结构的楼层剪力和楼层位移比普通结构小;隔震时,铅锌橡胶支座能够吸收地震能量,减小上部结构的地震反应,减小结构楼层剪力的同时增大结构的楼层位移;新型结构和普通结构均能满足规范要求,但新型结构具有更好的应用前景.New high-rise assembled honey comb steel grid box double-tube structure system is effective for such problems as earthquake. Response spectrum analysis and dynamic time-history analysis were carried out in this paper to analyze indexes such as storey shear force, storey displacement and wind resistance checking of the new structure in seismic isolation and non-seismic isolation environments respectively under the effect of frequent and rare earthquakes. The results were compared with those of the common structure. It is shown that, in non-seismic isolation environment, compared with the common structures, the new structure has smaller storey shear force and displacements;in seismic isolation environment, Pb-Zn rubber bearing can absorb seismic energy to reduce the seismic response of the upper structure and accordingly reduce storey shear force while increasing storey displacements. The new structure and common structure can both meet relevant specifications, but the new structure has better application prospect.
