摘要:
以远场长周期地震记录为输入,以隔震等效双线性SDOF体系为研究对象,研究了长周期地震强度指标与体系最大位移响应之间的相关性。首先,从太平洋地震工程研究中心(PEER)选取50条远场长周期地震记录作为输入,采用双线性力-位移关系曲线描述隔震支座的力学特性,根据生产厂家提供的支座参数确定体系的屈重比和支座的刚度比;其次,运用MATLAB进行编程求解,得到了与各地震记录对应的地震强度指标值和体系的最大位移响应;然后,采用Pearson方法对各地震强度指标与体系最大位移响应之间的相关性进行了统计研究。研究结果表明,远场长周期地震作用下,隔震结构的最大位移响应与加速度型指标和速度型指标的相关性较好,而与位移型指标的相关性最差;建议在进行隔震结构的抗震性能研究时,根据隔震前周期T1的取值范围选取Ic或PGV作为地震强度指标。
Abstract:
The far-field long-period ground motions were used as seismic input, the equivalent bilinear SDOF system was used as research object, the correlation between the seismic intensity measures of long-period ground motions and the maximum displacement responses of the SDOF were studied. Firstly, 50 long-period ground motion records were chosen from Pacific Earthquake Engineering Research Center (PEER) as seismic input. Bilinear force-displacement relation curve was adopted to respect the mechanical properties of isolation bearings. The ratio of yield strength and gravity and the yield stiffness ratio were decided according to isolation bearing parameters that provided dy manufacturers. Secondly, value of the seismic intensity measures for every ground motion and the maximum displacement responses of the system were calculated by using matlab. And then, the correlation between seismic intensity measures and the maximum displacement responses were obtained by using the Pearson statistical method. Research results show that the correlations of acceleration-related and velocity-related seismic intensity measure are better, while the correlations of displacement-related seismic intensity measures are the worst under far-field long-period ground motions. The seismic intensity measure Ic and PGV were proposed as the intensity measure according to pre-yield period of the base-isolated structure.
