美国高层建筑抗震性能化设计简介

Brief introduction of performance-based seismic design of high-rise buildings in America

简要介绍美国主要抗震性能化标准发展历程,并以TBI作为主要参考,介绍美国抗震性能化设计流程、两阶段设计方法,两水准性能目标制定、设计参数,并结合ARUP美国部分项目及CTBUH制定的performance-based seismic design for tall building所提供的部分案例,对美国抗震性能化设计进行了简要的介绍,最后概括总结了中美抗震性能化设计主要差异,以及抗震性能化设计的未来前景。

The development history of the main performance-based seismic design standards in America was briefly introduced,and TBI was taken as the main reference to introduce the performance-based seismic design process,two-stage design method,two-level performance goal formulation,and design parameters in America.The performance-based seismic design in America was also briefly introduced in combination with some cases provided by ARUP′s American projects and CTBUH′s performance-based seismic design for talk building.Finally,the main differences between performance-based seismic design in China and America and the future prospects of performance-based seismic design were summarized.
