  1. On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place

    本文試圖就上述的這兩大方面的內容,從以下三個角度進行了初步研究: 1 、縱槽向抗震性能分析1 )湯峪河吊桿拱支承結構的縱槽向地震效應較小;吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度,以及結構的整體性,故適當加大構件截面尺寸或提高砼標號,盡量降低結構的建築高度和重心,在構件連接和變截面處增設梗脅,按照約束混凝土的要求來加強箍筋的配置,增加砼的延性,以克服地震時構件連接和變截面處的應力集中造成的坡壞,並吸收大量的地震能量,從而起到隔震,減震的效果。

  4. 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震動記錄,採用兩步回歸法對地震動的各種能量參數進行回歸分析,找出地震動的能量參數隨震級、距離等參數的衰減關系,為基於能量的方法能夠應用到抗震設計及震害評估等實際工程中奠定基礎。
