Hysteresis Model for Reinforced Concrete Structures Considering Strength Deterioration due to Cyclic Loadings

利用已有的试验研究中得到的荷载-变形关系，建立了曲线滞回模型。该模型适用于具有曲线恢复力特征的大范围结构，如木结构或钢筋混凝土结构。木结构和钢筋混凝土结构的模型参数唯一的区别是滞回曲线拐点的受力水平不同。当参数确定充分且加载历史不是很偏心时，该模型精确地遵循了前人研究中显示的荷载-变形关系。

A curvilinear hysteresis model is developed using load-deformation relations obtained in previous experimental studies. The new model is applicable for wide-ranged structures which have curvilinear restoring force characteristics like wooden or R/C structures. The only difference between the model parameters of wooden and R/C structure is the force level of the inflection point of the hysteresis curve. The model precisely follows the load-deformation relations shown in previous studies when the parameters are adequately determined and the loading history is not very eccentric.
