【摘要】 竖向不规则超高层建筑由于竖向刚度变化大、体型不均匀、出现突变等,在大震作用下结构响应明显。通过某体型收进、立面开洞和底部带转换层的超限高层动力弹塑性计算分析,检验其结构布置的合理性和结构的抗震性能,反映其在大震作用下的受力特点和重点加强部位,以实现该结构的抗震性能设计目标,满足大震不倒的设计要求。更多还原

【Abstract】 Vertical irregularities are characterized by vertical discontinuities in the distribution of stiffness,irregular configuration and sudden changes,with significant seismic response.We reported a high-rise building with set-back, openings on facade and a transfer floor.The mechanical characteristics and focus part need be strengthened under earthquake were studied by elastic-plastic dynamic analysis of this structure.The validity of the structure arrangement and the seismic performance of the structure were also be checked by nonlinear dynamic analysis.The seismic capability objective of this structure was achieved eventually.更多还原
