在役受腐蚀钢筋混凝土结构由于受到外界侵蚀介质的影响，其抗力水平随着结构服役时间的推移而处于不断的衰减过程中，在结构使用功能保持不变情况下结构可靠度逐渐降低，因此在确定设计基准期内难以完成预期设计功能。基于结构控制截面的强度衰减规律，从《建筑结构设计统一标准》出发，研究建立了不维修受腐蚀结构综合考虑其直接投资和服役效益的最佳设计可靠度指标的决策方法，对侵蚀性介质环境下工作的建筑结构的可靠性设计提供了一种建设性的理论指导
Corrosion-resisting reinforced concrete structures in service are affected by externally eroding media, their resistance levels are in constant attenuation with the passage of structure service time, and the structural reliability is gradually reduced when the structural use function remains unchanged. It is difficult to complete the intended design function during the design reference period. Based on the strength attenuation law of the structure control section, starting from the “Unified Standard for Building Structure Design”, a decision method for the optimal design reliability index without considering the direct investment and service efficiency of the corrosion structure without maintenance is established and studied. The reliability design of the building structure working in the environment provides a constructive theoretical guidance
