Performance-based seismic design (PBSD) has been recognized as a framework for designing new buildings in the United States in recent years. Various guidelines and standards have been developed to codify and document the implementation of PBSD, including “Seismic Evaluation and Retrofit of Existing Buildings” (ASCE 41-17), the Tall Buildings Initiative’s Guidelines for Performance-Based Seismic Design of Tall Buildings (TBI Guidelines), and the Los Angeles Tall Buildings Structural Design Council’s An Alternative Procedure for Seismic Analysis and Design of Tall Buildings Located in the Los Angeles Region (LATBSDC Procedure). The main goal of these documents is to regularize the implementation of PBSD for practicing engineers. These documents were developed independently with experts from varying backgrounds and organizations and consequently have differences in several degrees from basic intent to the details of the implementation. As the main objective of PBSD is to ensure a specified building performance, these documents would be expected to provide similar recommendations for achieving a given performance objective for new buildings. This article provides a detailed comparison among each document’s implementation of PBSD for reinforced concrete buildings, with the goal of highlighting the differences among these documents and identifying provisions in which the designed building may achieve varied performance depending on the chosen standard/guideline. This comparison can help committees developing these documents to be aware of their differences, investigate the sources of their divergence, and bring these documents closer to common ground in future cycles.

近年来，基于性能的抗震设计（PBSD）被公认为设计新建筑物的框架。已开发出各种准则和标准来整理和记录PBSD的实施，包括“现有建筑物的地震评估和改造”（ASCE 41-17），《高层建筑计划》基于高层建筑的基于性能的地震设计指南（TBI指南）），以及洛杉矶高层建筑结构设计委员会针对位于洛杉矶地区的高层建筑进行地震分析和设计的替代程序（LATBSDC程序））。这些文件的主要目的是规范实践工程师的PBSD实施。这些文件是由来自不同背景和组织的专家独立开发的，因此从基本意图到实施的细节在各个程度上都有差异。由于PBSD的主要目标是确保特定的建筑性能，因此这些文件有望为实现新建筑的给定性能目标提供类似的建议。本文对钢筋混凝土建筑的PBSD的每个文档实施方式进行了详细的比较，目的是强调这些文档之间的差异，并确定根据所选标准/指南，设计的建筑可能实现不同性能的规定。
