拱高
The analysis on ground motion response of stone arch bridge was done according to typical seismic waves in different site and specification-based artificial waves. The effects of different arch axis and rise-span ratio on seismic behavior of stone arch bridge were discussed.
针对不同场地的典型地震波和基于规范生成的人工波,对石拱桥的地震动反应进行了分析,讨论了不同拱轴线和矢跨比对石拱桥抗震性能的影响。
Moreover, parameter analysis of rise-to-span ratio of truss arch bridge with oblique tension link and span ratio of slant legged rigid frame bridge are carried out in four kinds of span which are 20m, 30m, 40m and 50m.
分别对其中最常用的斜拉杆式桁架拱桥和斜腿刚架桥进行了跨径为20m、30m、40m和50m时的矢跨比和分跨比参数分析。
