Comparison of Chinese and U.S. Technical Standards for Steel Structures: Seismic Action and Seismic Design
-
摘要: 地震作用计算与抗震安全性评价方法是中美建筑钢结构设计标准的重要内容。中美工程建设标准都对建筑结构的抗震设防要求、地震动参数选择、地震作用计算方法、抗震钢结构体系、钢构件和节点的抗震安全性评价方法等内容做出了详细规定。为此梳理和总结了中美建筑钢结构抗震相关的技术标准,分析和比较了地震作用计算与钢结构抗震设计部分条文内容,有助于理解中美建筑钢结构的抗震设计要求,对完善中国相关标准规定具有参考价值。Abstract: Seismic action and seismic safety evaluation are essential in the current design standards for building steel structures in both China and the U.S. Both Chinese and U.S. standards specify the seismic design requirements for building structures, the selection of ground motion parameters, methods for calculating seismic action, seismic systems for steel structures, and seismic safety evaluation methods for steel members and joints. This paper summarizes the relevant technical standards for seismic design of building steel structures in China and the U.S., and analyzes and compares certain provisions. The aim is to improve the understanding of seismic design requirements in both countries and to provide a reference for revising relevant provisions in Chinese standards.
