高墩抗震性能评估的适用地震动强度参数研究
Research on Appropriate Intensity Measure of Tall Pier Seismic Performance Estimation
摘要
Abstract
In order to effectively estimate the seismic performance of RC tall pier,53 real ground motion records were chosen to establish a record base,and three pier models with different natural period were established.The applicability of the intensity measure,which considers the higher modes for evaluating the seismic performance of the reinforced concrete pier was studied.The IDA curves and standard deviation including normal distribution and lognormal distribution can be obtained by using incremental dynamic analysis and statistical analysis,which can also derive standard deviation of response and log response of three models curves changing with intensity measure.The results show that proposed intensity measure can effectively estimate the seismic performance of tall pier,which can be an excellent foundation of further study of pier seismic performance estimation.关键词
