  • Firstly , a practical reliability design method of rc structure with expected service life is proposed in this paper
    首先,本文进行了预期使用期钢筋混凝土结构可靠度实用设计方法的研究。
  • 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
    根据我国现行建筑结构可靠度设计原理,考虑耐久性退化影响因素,设计了抗力统计参数与我国调查结果一致的五种代表性钢筋混凝土构件,考虑多种荷载效应组合以及不同荷载效应比,研究了不同使用期内代表性构件的可靠度变化规律;为保证预期使用期内结构可靠度水平仍可满足现行规范要求,提出了根据预期使用期和抗力衰减幅度确定结构设计可靠度指标的方法,并通过优化的方法确定了预期使用期内的耐久性折减系数,给出了预期使用期结构可靠度设计的实用设计方法。
