复杂高层建筑结构抗震设计方法研究现状与展望

Research status and prospects of seismic design method for complicated high-rise building structure

近些年出现了一大批复杂高层建筑,其在地震作用下受力更为复杂,更容易发生薄弱层破坏。目前我国规范的设计主要是针对规则结构,对于不规则复杂结构主要通过限制其不规则程度来进行控制。本文结合复杂高层建筑结构震害,分析了复杂高层建筑结构破坏机制,重点探讨了当前高层建筑结构基于性能化抗震设计方法存在的问题,给出了针对复杂高层建筑结构抗震设计方法的相关建议。

Recently,a large number of complicated high-rise buildings which force are more complicated under earthquake and prone to weak layer damage.At present,our country’s codes are mainly for the regular structures,for irregular complicated structures,are controlled by limiting their degree of irregularity.Based on the seismic damage of complicated high-rise building,the damage mechanism of complicated high-rise building is analyzed,the problems existing in performance-based seismic design methods are discussed,suggestions of seismic design methods for complicated high-rise building structures are provided.
