［摘要］风荷载作用下的层间位移角作为高层建筑结构控制参数对设计的经济性有着重要的影响，但不同国家及地区规范对层间位移角控制却不尽相同。世界各地的高层建筑在各自的规范控制下正常发挥使用功能，说明各规范的层间位移角限值均在合理的范围内。针对不同高度的框架结构、框-剪结构、剪力墙结构和框-筒结构在风荷载作用下的层间位移角，取相同结构尺寸、场地条件和风速，将中国大陆地区规范与欧洲、美国、澳新、日本、中国台湾地区和中国香港地区等规范进行分析对比。对于框架结构，发现欧洲、美国、澳新和中国大陆地区规范要求较严格，日本、中国台湾地区和中国香港地区规范要求较宽松；对于以剪力墙为主要抗侧力构件的结构，中国大陆地区规范要求最严格。按中国大陆地区和中国香港地区规范分别对位于中国香港地区的建筑进行计算和设计，并对其结果进行分析对比，发现中国大陆地区规范要求更严格。根据分析结果，建议中国大陆地区不区分结构形式与高度，将风荷载作用下的结构层间位移角限值定为1/450。

Abstract:The story drift ratio under wind load is a  control parameter  of high-rise building structure with important influence on the economy, but the control of story drift ratio is different in codes of different countries and regions. The high-rise buildings around the world are functioning normally under the control of their respective codes, indicating that the story drift ratio limit of each code is within a reasonable range. The story drift ratios of frame structure, frame-shear wall structure, shear wall structure and frame-corewall structure of different heights under the wind load were studied under the same conditions of structural size, site condition and wind speed. The results were analyzed and compared for codes from mainland China, Europe, the United States, Australia-New Zealand, Japan, Taiwan (China), and Hong Kong (China). For frame structures, it is found that the code requirements of Europe, the United States, Australia-New Zealand and mainland China are stringent, and the code requirements of Japan, Taiwan (China), and Hong Kong (China) are relaxed. For the structure with shear wall as the main component to resist lateral forces, code requirement of mainland China is the most stringent. A building in Hong Kong (China) was calculated and designed according to the codes of mainland China and the codes of Hong Kong (China) respectively, and the results were compared. It is found that the code requirement  of mainland China is more stringent. According to the analysis results, it is recommended that the structural form and height are not distinguished in mainland of China, and the story drift ratio limit under the wind load is set to 1/450.

Keywords:high-rise building; story drift ratio limit; comparison of codes from different countries and regions; calculation of wind load
