| 摘 要： | 采用ANSYS11.0和MIDAS/CIVILV7.4.1,建立了一个整体模型和三个局部模型,对一下承式单索面钢箱叠合梁钢管砼系杆拱桥的钢管混凝土拱进行了局部分析。对比研究了主拱斜撑的两种截面型式对其内力的影响,重点关心在最不利荷载工况下主拱钢管和斜撑钢管的应力大小。计算结果表明:钢管混凝土拱设计合理可靠,为相似结构的设计与施工提供参考。 |
| 关 键 词： | 系杆拱桥 钢管混凝土拱 斜撑 |

| Abstract: | In this paper,based on Finite Element Software ANSYS11.0 and MIDAS/CIVIL V7.4.1,a integral model and three partial models were set up to analysis concrete filled steel tubular arch of a steel box composite beam and concrete filled steel tubular tied-arch bridge with single cable plane and suspended road.Comparative studying the influence of two kinds of cross-section of inclined brace on its internal forces and focusing on the stress level of main arch and inclined brace in the most harmful load condition.T... |
| Keywords: | tied-arch bridge concrete filled steel tubular arch inclined brace |
