摘要
讨论了钢筋混凝土框架结构层间极限变形角的近似概率特性,考察了大震作用下20余幢钢筋混凝土框架结构薄弱层的层间位移可靠度水平,从而为直接基于位移可靠度的抗震设计中层间目标位移可靠度的确定提供了一定依据。
The probabilistic properties of ultimate interstory drift ratio for RC frame structure is discussed. The reliability level of interstory drift for weak stories of more than 20 existing RC frame structures under major earthquake is investigated. This provides a foundation for determining the target reliability of interstory drift which will be used in the direct displacement reliability-based seismic design.
