In this article, damage states for Reinforced Concrete (RC) elements of framed RC buildings, including beams, columns, and joints, were presented and defined. For this purpose, the benchmark RC structures were considered, and details of their members were extracted. Each of the elements was separately modeled, and a pushover load was applied until the observed force/moment reached the predicted amount obtained by verified soft computing techniques. Consequently, the capacity curves were derived and scaled to specify the average curves and also to determine their corresponding equations. Using these formulations, damage states were defined for the considered structural elements. The ability of the proposed damage states was also investigated for six RC frames by eighteen three-dimensional time-history analyses as a numerical study. The framework proposed in this research can be able to present a better description of the damaged RC frame rather than the existing models, which only consider the drifts. Finally, it could be declared that the introduced damage states have great potential for seismic studies related to the behavior of structural elements.

框架钢筋混凝土建筑中结构元件的破坏状态的新定义

在本文中,提出并定义了框架式RC建筑物中钢筋混凝土(RC)单元的破坏状态,包括梁,柱和接缝。为此,考虑了基准钢筋混凝土结构,并提取了其成员的详细信息。对每个元素分别进行建模,并施加推覆载荷,直到观察到的力/力矩达到通过验证的软计算技术获得的预测量为止。因此,得出了容量曲线,并按比例缩放以指定平均曲线并确定其相应的方程式。使用这些公式,为考虑的结构元素定义了破坏状态。还通过十八次三维时间历史分析作为数值研究,对六个RC框架研究了建议的损坏状态的能力。这项研究中提出的框架可以更好地描述受损的RC框架,而不是仅考虑漂移的现有模型。最后,可以断言,引入的损伤状态对于与结构元素的行为有关的地震研究具有很大的潜力。
