摘　　要：为适应不同使用年限建筑结构设计和评估的需要,从等超概率原则和结构可靠度角度出发,探讨不同使用年限影响系数的取值。结合现行设计规范表达式和楼面活荷载、地震作用的概率模型和统计参数,得到目标可靠度指标与随机变量设计值之间的关系,给出不同使用年限的可变荷载对应的使用年限影响系数。In order to meet the needs of design and assessment of different age structure, and based on the super probability principle and structure reliability, the different life influencing coefficients are discussed. Combining with probability model and its statistical parameters, the current design code of expressions and floor live load, earthquake action, the relationship between the target reliability index and the design value of random variables are put forward. The service life of influence coefficient variable load corresponding to different age is put forward. The research result will present reference for the design and safety assessment of structure building.
