在拱梁组合桥梁设计和施工分析中,确定成桥状态时的吊杆张拉力非常关键.采用空间杆系有限元分析模型,对结构新颖的外倾式空间组合拱桥的成桥吊杆张拉力运用三种分析方法进行了分析计算对比,获得了该组合拱桥的成桥合理的张拉力.分析方法可为其它组合拱桥提供参考.
在拱樑組閤橋樑設計和施工分析中,確定成橋狀態時的弔桿張拉力非常關鍵.採用空間桿繫有限元分析模型,對結構新穎的外傾式空間組閤拱橋的成橋弔桿張拉力運用三種分析方法進行瞭分析計算對比,穫得瞭該組閤拱橋的成橋閤理的張拉力.分析方法可為其它組閤拱橋提供參攷.

In the design and construction analysis of combination arch beam bridge, it's crucial to ascertain the tensioning force in suspenders in finished state.Space bar finite element model is used in order to analyze and calculate the tensioning force in suspender in finished stated of a new style extroversion spatial arch bridge. The tensioning force of combination arch Bridge is determined with three different methods.Reference for constructions of similarly arch bridge is provided.
