  1. 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

    本文基於對大歐洲強記錄的研究,分析了地動豎向與水平向分在峰值加速度、反應譜值、頻譜周期等參數方面的差異,以及這些參數與場地、源機制、中距的,得到了以下有意義的結果和結論:在本文分析的地記錄中大約1 / 3的記錄加速度峰值比大於2 / 3 ,豎向地動分的作用不可低估;在短周期,豎向地動影響數的最大值僅取為水平向地動影響數最大值的65 %是偏於不安全的,可以考慮按周期分段採用不同的折減數;我國現行抗規范中設計反應譜特徵周期的取值偏低,可是偏於不安全的;豎向與水平向地動分卓越周期的比值在0 . 7 - 0 . 9之間,豎向設計反應譜的特徵周期應有單獨規定。
  2. Based on 266 strong ground motion records from 15 earthquakes in america, an attenuation relationship was used to relate energy spectra to earthquake magnitude, source - to - site distance, and site class. the purpose of this study is to make a foundation of energy - based design and seismic hazard analysis. the main achievements of this study could be summarized as follows : 1

    本文的主要工作就是利用所掌握的地動記錄,採用兩步回歸法對地動的各種參數進行回歸分析,找出地動的參數隨、距離等參數的衰減,為基於的方法夠應用到抗設計及害評估等實際工程中奠定基礎。
