Structure will be a kind of ductile structure with advanced seismic behavior . based on the tests of 25 elements of hollow shear wall r . c . structure and 16 hollow shear wall , we had accomplished pseudo - dynamic tests which employed el - centro wave with different input peak acceleration and pseudo - static test of 1 / 2 . 8 scale model 10 - story building 在已完成了25个基本空心剪力墙试件和16个墙片的试验基础上，进行了空心剪力墙结构十层楼房1 2 . 8的模型拟动力、拟静力试验，拟动力实验采用不同输入峰值加速度的el - centro ( ns )波。
The records we used are mainly from three parts : strong ground motion data before 1992 ' s ; data from scec ( south california earthquake catalog ) ; nsmp ( national strong motion project ) . after we developed the attenuation laws , we analysis the attenuation characteristics for the pga and sa with different damping ratio . here we mainly concentrate on the effect of the distance and the magnitude 在回归出中小地震的衰减关系后，本文对峰值加速度(水平向与垂向) 、加速度反应谱(阻尼比分别为0 . 005 、 0 . 02 、 0 . 05 、 0 . 1 、 0 . 2 )的衰减特性进行了分析，影响因素主要考虑了震级与距离这两个方面。
In addition , effects of several factors such as local site conditions , focal mechanism , epicentral distance and seismic magnitude on these parameters are discussed , and several significative results and conclusions are obtained . in all records there are about 1 / 3 vertical ground motion ’ s peak acceleration bigger than 2 / 3 of the corresponding horizontal one , so the action of vertical ground motion should not to be underestimated . vertical design response spectrum equals that the horizontal design response spectra times 65 % is probably unsafe when period is short , and suggest adopting different coefficients when at different periods 本文基于对大量欧洲强震记录的研究,分析了地震动竖向与水平向分量在峰值加速度、反应谱值、频谱周期等参数方面的差异,以及这些参数与场地、震源机制、震级和震中距的关系,得到了以下有意义的结果和结论:在本文分析的地震记录中大约1 / 3的记录加速度峰值比大于2 / 3 ,竖向地震动分量的作用不可低估;在短周期,竖向地震动影响系数的最大值仅取为水平向地震动影响系数最大值的65 %是偏于不安全的,可以考虑按周期分段采用不同的折减系数;我国现行抗震规范中设计反应谱特征周期的取值偏低,可能是偏于不安全的;竖向与水平向地震动分量卓越周期的比值在0 . 7 - 0 . 9之间,竖向设计反应谱的特征周期应有单独规定。
