摘　　要：风荷载是结构设计的重要荷载之一,中国和菲律宾规范关于风荷载的规定有所不同,通过研究两国规范中关于风荷载规定的异同,可为相关项目进行结构设计提供指导。在风荷载计算方法、风荷载基本参数方面比较中菲两国规范的异同,并选取多、高层建筑作为实例,分别按中菲规范计算风压设计值,并进行对比。对比结果表明,中菲规范在风荷载的计算方法上基本相同,但在风荷载的基本参数上有所区别,不同高度的建筑物按中菲规范计算得到的风压设计值也有所不同。Wind load is one of the important loads in structural design.The regulations on wind load are different in the codes of China and the Philippines.Through studying the similarities and differences in the regulations on wind load in the codes of the two countries,it can provide guidance for the structural design of related projects.In terms of wind load calculation methods and basic parameters of wind load,the differences and similarities between Chinese and Philippine codes are compared.Multi-storey and high-rise buildings are selected as examples,and the design values of wind pressure are calculated according to the Chinese and Philippine codes respectively.The comparison results show that the wind load calculation methods of the Chinese and Philippine codes are basically the same,but there are differences in the basic parameters of the wind load.For buildings of different heights,the design values of wind pressure calculated according to the Chinese and Philippine codes are also different.
