基于构件性能的钢筋混凝土结构抗震评估方法研究

基于钢筋混凝土构件抗震性能指标限值，建立构件抗震性能与整体结构抗震性能的判别关系准则，提出基于构件性能的结构抗震评估方法。分别利用基于位移的抗震评估方法和文中推荐的抗震评估方法，对3个典型的填充墙框架在罕遇地震作用下的抗震性能进行评估。结果表明：基于构件性能的抗震评估方法能够考虑结构构件和非结构构件损伤对结构整体抗震性能的影响，解决规范推荐的抗震评估方法中存在的整体结构抗震性能与构件自身损伤关系不明确的问题；是否考虑填充墙损伤的影响对结构抗震性能评估结果差别较大，在实际工程中应考虑填充墙的损伤对结构抗震性能的影响。

Research on component-performance-based seismic assessment of RC structures

Based on the seismic performance index research of components of RC structures, this paper presents a seismic performance evaluation method of RC structures from the perspective of components by establishing the relationship on seismic performance between components and the overall structure. Three typical examples were selected to be evaluated by displacement-based assessment method and the recommended method respectively. The results prove that the proposed approach can consider the influence of structural/nonstructural components damages on seismic assessment and clarify the ambiguous relationship between overall structure and components in codes, and considering the influence of nonstructural components (like infilled walls) or not, leads to obvious different seismic assessment results of the overall structures. It is suggested that the influence of nonstructural components should be considered in engineering applications.
