| Abstract: | 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. |
