超限高层结构抗震性能化设计方法探讨

Discussion on Performance-based Seismic Design Method of Transfinite High-rise Structure

高层建筑在提高土地资源利用率方面有突出的作用,但其建设规模大,质量要求高,可因外部作用而发生局部失稳乃至坍塌等事故,因此如何有效提高建筑的抗震性能是值得重点探讨的内容。为保障高层建筑的安全使用,亟需加强对抗震设计方法的探索,明确对抗震效果造成影响的关键因素,确定适用于高层建筑的抗震设计方法,制定抗震方案并落实到位,切实提高高层建筑的抗震性能。

High-rise buildings play a prominent role in improving the utilization rate of land resources,but their construction scale is large,the quality requirements are high,and accidents such as local instability and even collapse can occur due to external effects.Therefore,how to effectively improve the seismic performance of buildings is a content worthy of focus.In order to ensure the safe use of high-rise buildings,it is urgent to strengthen the exploration of seismic design methods,clarify the key factors affecting the seismic effect,determine the seismic design methods applicable to high-rise buildings,formulate and implement the seismic plan,and effectively improve the seismic performance of high-rise buildings.
