The resistance attenuation of each element is considered in the design process, and the statistical parameters of the elements are assumed to be the same as the investigated results of china. in the process of the calculating of the element reliability attenuation in expected service life, several load combination and different load ratio of dead load to live load are considered. in order to ensure that structure reliability in expected service life satisfies the requirement of today ’ s code, a method of choosing the initial reliability index of structure basing on the length of expected service life and the structure resistance attenuation is proposed and the corresponding durability reduction factor is chosen by an optimum algorithm
根據我國現行建築結構可靠度設計原理，考慮耐久性退化影響因素，設計了抗力統計參數與我國調查結果一致的五種代表性鋼筋混凝土構件，考慮多種荷載效應組合以及不同荷載效應比，研究了不同使用期內代表性構件的可靠度變化規律;為保證預期使用期內結構可靠度水平仍可滿足現行規范要求，提出了根據預期使用期和抗力衰減幅度確定結構設計可靠度指標的方法，並通過優化的方法確定了預期使用期內的耐久性折減系數，給出了預期使用期結構可靠度設計的實用設計方法。
