美国性能设计发展现状概述及其与我国规范的对比

Development of Performance-based Seismic Design in America and its Comparison with Chinese Codes

摘要: 结合美国多本现行性能设计规范，叙述了性能设计的发展背景，阐述了进行性能设计的意义并与传统基于规范条文的设计方法进行了对比。对性能设计中涉及的性能目标、接受准则等主要问题作了细致阐述，介绍了性能设计发展的两个新方向：基于概率化表述的性能目标，和采用全新性能指标的下一代性能设计方法。

Abstract: Development background of PBSD (Performance-Based Seismic Design) is stated. The advantages of PBSD are discussed and it is compared with traditional code-based design. Major issues in PBSD such as performance objectives and acceptance criteria are elaborated. Two development trends of PBSD, probabilistic performance objectives and next-generation PBSD which adopts novel performance measurements, are introduced.
