The retortion influence of base isolating building and base fixed building under horizontal earthquake effect is discussed, and the difference between them under the same condition is compared.
本文介绍了减震结构的动力特性,并计算了结构在地震作用下各层的位移、速度、加速度和剪力等地震反应;分析了结构在同时受到两个水平方向地震作用时结构的地震反应,从与抗震结构的对比中可见其优越性;选用了不同场地上的地震波模拟了各类场地上的地震作用,分析比较了不同的场地对建筑物减震效果的差异;分析了橡胶垫水平刚度的变化对动力分析结果所造成的影响,提出了在橡胶垫恢复力曲线中,按线性模型进行简化计算的条件;讨论了隔震垫的设置位置,比较了隔震垫设置在首层柱的底部和设置在其它位置的区别;分析了减震结构在连续经历多次地震时(即在地震后、较大余震作用下)是否仍然能够减震的问题;并对水平地震作用下,减震结构和抗震结构的受扭情况进行了讨论,比较了同等条件下两种结构的区别。

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.
在系统分析并筛选出华北地区地震频度、地震活动标度、mf值、调制比、b值、D值、η值、地震活动强度熵和地震活动时间熵等映震较好的9项测震学参数基础上,应用综合异常指数方法,分别计算了它们各自的地震异常指数时序值,进而合成得到华北地区测震学综合异常指数时序曲线,通过研究其地震短期异常特征,给出了华北地区M≥5.8地震短期综合预测的判据指标,经R值评分检验表明,该指标具有较好的地震预测效能。
