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。
Vertical irregular tall buildings due to the vertical stiffness changes, uneven body, a sudden change, under the action of the earthquake obvious structural response. Through the calculation and analysis of over-limit high-rise dynamic elasto-plasticity of a certain type of building, open hole in the facade and bottom with transfer layer, the rationality of structural arrangement and the seismic performance of the structure are verified, and its stress characteristics under large earthquake and Focus on strengthening the site in order to achieve the design of seismic performance of the structure to meet the design requirements of the earthquake does not fall.
