| Abstract: | 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. |
