| 摘 要： | 分别以主跨180 m的波形钢腹板矮塔斜拉桥和PC箱梁矮塔斜拉桥为研究对象,通过数值模拟分析,比较2种不同主梁的矮塔斜拉桥在恒裁、预应力荷载以及温度荷载作用下结构的受力特性.结果表明,与PC箱梁矮塔斜拉桥相比,虽然波形钢腹板矮塔斜拉桥由混凝土收缩徐变引起主梁钢束预应力损失大,但其主梁的预应力效率更高,成桥状态下预应力储备...

| Abstract: | with short tower cable-stayed bridge of corrugated steel webs with a 180 m-log main span and PC box girder short tower cable-stayed bridge as the objects of research,this paper compares stress characteristics of structures of short tower cable-stayed bridges of two different girders under the effects of constant load,prestressed load and temperature load via numerical simulation analysis.Results show that although prestress loss of steel beams of girder of short tower cable-stayed bridge of corrugated steel... |
