摘要
对于公路桥涵钢筋混凝土和预应力混凝土结构构件的设计计算,其采用的是近似概率极限状态设计法,规定设计计算应满足承载能力和正常使用两种极限状态的各项要求。在桥涵的设计计算中不同安全等级是用桥梁结构的重要性系数来体现的,为了使不同安全等级的桥梁结构具有规定的可靠度而采用的作用效应系数的分项系数。
For the design and calculation of highway bridges reinforced concrete and prestressed concrete structural members, it uses approximate probability limit state design method and provisions to meet the requirements of two limit state of normal use and carrying capacity. In design and calculation of highway bridges, importance coefficient of bridge structure reflects the different level of security, and partial coefficient of effect coefficient is used to make bridge structure with different level of security has specified reliability.
