摘　　要：为了研究设计工作年限100年的建筑结构的设计方法,文章首先明确设计工作年限的定义和取值,其次对比两种工作年限条件下结构的地震作用、可变荷载取值、耐久性设计的差异,整理出100年设计工作年限的结构设计要点。同时选取三种不同结构类型的建筑,通过计算对比分析,比较两种不同设计工作年限条件下的建筑在构件尺寸、地震效应、结构造价方面的差异。得出结论设计工作年限取值要与国民经济发展水平和结构安全度的要求相适应,不可盲目提高。In order to study the design method of the building structure with 100 years of working life, this paper firstly clarified the definition and value of the design working life, and then compared the difference of the seismic action, variable load value and durability design of the structure under the two working life conditions, sorted out the key points of the structural design with 100 years of working life. At the same time, three different structural types of buildings are selected. Through calculation and comparative analysis, the differences in component size, seismic effect and structural cost of buildings under two different design working years are compared, it is concluded that the value of design working life should meet the requirements of national economic development level and structural safety degree, and should not be increased blindly.

关 键 词：设计工作年限 地震作用 可变荷载 结构耐久性
