摘要:
RC核心筒是高层混合结构中应用广泛的结构单元体系，为体现构件损伤向结构损伤迁移转化的多尺度效应，基于数 值模拟方法，在分析构件耗能权重的基础上，建立了结构单层地震损伤模型；通过对结构单层损伤与整体结构破坏之间的关系进行分析，采用位置权重系数与结构单层损伤指数权重系数二者组合的形式作为结构层损伤权重系数，建立了能够反映构件损伤、楼层损伤以及整体结构损伤三者之间迁移演化规律的RC核心筒地震损伤模型，并给出了RC核心筒的损伤状态及相应的损伤指数范围．计算结果与试验结果的对比表明，建立的地震损伤模型能够较好地描述核心筒结构的地震损伤演化过程与损伤程度，并反映构件损伤、局部结构损伤以及整体结构损伤三者之间迁移演化规律，研究结果可为混合结构抗震性能评估提供参考．
Abstract:
RC core walls is a widely used structural unit in high-rise hybrid structure. In order to study the multi-scale effect of migration and transformation from member damage to structure damage, based on numerical method, the storey damage model was established by introducing energy weighting coefficient of members. Through analysis the relation between storey damage and structure damage, the global damage model, which could reflect migration and evolution law from member damage to local damage and global damage, was established by using the storey weighting coefficient is a combination of location weighting coefficient and storey damage weighting coefficient. The damage states and corresponding damage index range of RC core walls were defined by combining the damage indexes. Comparison of the calculated results with test results indicates that the proposed seismic damage model can appropriately describe the damage evolution of RC core walls, and the relationship between the local component damage and global structure damage is revealed. The results may well serve as a reference on seismic performance evaluation for hybrid structure.
