摘　　要：针对现行的建筑结构设计可靠性问题进行分析探讨,建议把设计使用年限与结构安全等级一一对应,明确不同设计使用年限建筑结构的可靠度;建议现行建筑结构可靠度计算方法采用新的变量考虑设计和施工质量的影响;建议采用中震设计方法,荷载效应采用标准值,采用材料标准值计算构件承载力,让设计人员更加直观准确把握抗震结构的可靠度。This paper analyzes and discusses the reliability of current building structure design.It is suggested that the design service life and structural safety level should be one-to-one,and the reliability of building structure with different design service life should be defined.It is suggested that new variables should be used to consider the influence of design and construction quality in the current calculation method of building structure reliability,and the medium earthquake design method should be adopted,and the load effect should be adopted Standard value,using the standard value of materials to calculate the bearing capacity of components,so that designers can more intuitively and accurately grasp the reliability of the seismic structure.

关 键 词：建筑结构可靠度 结构设计使用年限 中震设计 重要性系数 结构安全等级
