摘要为了解巨型组合结构体系中钢管混凝土格构式柱的地震损伤情况，通过对4根四肢钢管混凝土格构柱低周往复荷载试验，得出了四肢钢管混凝土格构柱在低周往复荷载下的破坏形态和构件损伤特征。在试验分析基础上，对经典的Park-Ang损伤模型进行了修正，提出了适用于四肢钢管混凝土格构柱的损伤指数和耗能因子计算公式；并根据试验现象和各阶段特征，选取了经典的Park-Ang损伤模型、基于能量的损伤模型和改进的Park-Ang模型进行了对比研究。结果表明：改进的Park-Ang模型能较好的判断四肢钢管混凝土格构柱的损伤程度，且通过损伤值可将构件损伤划分为是否可修、不可修但未破坏和不可修且将破坏三个阶段，并以损伤值0.4作为划分试件是否可修的界限。

Abstract：To enable a better understanding of the damage and aseismic performance of these concrete filled steel tubular (CFST) laced columns, four CFST laced columns consisting of 4 main steel-concrete tubes were tested under cyclic loading. Failure modes and damage characteristics were studied based on the results from the lateral cyclic loading tests. Based on the analysis of experiments, the traditional Park-Ang damage was revised. And calculating formulas of damage index and energy dissipation factor, which is suitable for concrete filled steel tubular laced columns in a giant composite structure system, is established. According to the experimental phenomenon and the characteristics of each stage of the specimen through loading to failure, the calculation results among Park-Ang damage model, the energy-based damage model and the revised Park-Ang damage model were compared. The results shows that the damage degree of the concrete-filled steel tube lattice columns can be better evaluated by the improved Park-Ang model, and the damage value could be divided into repairable, unrepairable but undamaged, and unrepairable. The damage value of 0.4 is suggested as the critical value of whether the specimen can be repaired or not.
