摘　　要：风荷载计算是建筑结构荷载设计的重要内容之一,不同国家和地区的荷载规范体系不尽相同。目前,广东省风荷载设计规范按照《建筑结构荷载规范》(GB 50009—2012)实行,香港地区按照2019年新修订的荷载规范实行。从计算方法和基本参数两方面比较广东省与香港地区荷载规范的中风荷载取值的异同;通过编程实现粤港地区建筑结构风荷载计算。对一超高层建筑工程案例进行结构设计风荷载的分析,获得了两地顺风向风荷载、横风向风荷载以及基本风压等重要数据,比较计算结果差异,发现香港地区建筑结构在设计过程中采用的风荷载比广东地区更大,引起该差异的其中一个原因是参考风压取值不同。Calculation of wind load is one of the important steps in the load design of building structures.Wind load codes in different countries and regions are not all the same.At present,the wind load design in Guangdong Province is implemented in accordance with the Load code for the design of building structures(GB 50009—2012),while the wind load code implemented in Hong Kong is a newly revised edition in 2019.The similarities and differences of wind load values in load codes of Guangdong Province and Hong Kong were compared from two aspects of calculation methods and basic parameters.Wind load calculation of building structure in Guangdong and Hong Kong area was realized through programming.The structural design wind load analysis of a super high-rise building engineering case was conducted to obtain important data such as downwind wind load,cross-wind wind load and basic wind pressure in the two places.Comparing the difference in the calculation results,it is found that the wind load used in the design process of the building structure in Hong Kong is greater than that in the Guangdong Province.One of the reasons for the difference is that the reference wind pressures are different.
