【摘要】：基于性态的抗震设计在国际上已被广泛采用,它被认为是未来抗震设计的主要指导思想。但是现行的基于性态的抗震设计主要针对的是结构构件的性态设计,对非结构构件的性态设计考虑不足,而非结构构件基于性态的抗震设计是完整实现整体建筑结构"基于性态抗震设计"的组成部分。首先对非结构构件的分类进行了重新梳理;分析了不同类别非结构构件的震害表现,总结了非结构构件的破坏模式及震害反应特征,并对相应的控制指标进行了说明;在此基础上,尝试给出了考虑非结构构件的建筑抗震设防目标,绘制了相应的非结构性态目标矩阵;最后,将整体建筑结构的性态目标进行了分解,以期为完整地实现包括结构、非结构的建筑整体的抗震性态设计框架奠定基础。
[Abstract]:Seismic design based on behavior has been widely used in the world, and it is considered to be the main guiding ideology of seismic design in the future. However, the current seismic design based on behavior is mainly aimed at the performance design of structural members. Insufficient consideration is given to the performance design of unstructured members. The non-structural component based seismic design is the integral part of the whole building structure "performance-based seismic design". Firstly, the classification of non-structural members is reorganized. The earthquake damage performance of different kinds of non-structural members is analyzed, the failure mode and response characteristics of non-structural members are summarized, and the corresponding control indexes are explained. On this basis, the paper tries to give the seismic fortification target of buildings considering non-structural members, and draws the corresponding non-structural target matrix. Finally, the performance target of the whole building structure is decomposed in order to lay a foundation for the complete seismic design frame of the whole building including the structure and the non-structure.
