钢—混组合曲线连续箱梁桥受力性能研究
|
摘要
钢-混组合曲线箱梁桥是混凝土面板与钢箱梁共同受力的一种新型组合结构,因其具有刚度大、抗震性能好、建筑高度小以及施工快速等优点,所以在西方发达国家得到了广泛的应用。在现在交通运输的发展和城市基础设施的建设蓬勃发展的今天,该类桥型势必会得到越来越广泛的应用。因此,本文对一座三跨钢-混组合曲线连续箱梁桥受力性能的研究,具有重要的现实意义。
本文介绍了曲线梁桥在国内外的应用和研究现状,并介绍了关于曲线梁桥的计算分析理论,对曲线梁桥的构造与受力特点及分析方法有一个初步的认识。为了研究钢-混组合曲线连续箱梁的受力性能,运用有限元软件ANSYS,对一座三跨钢-混组合曲线连续钢箱梁进行了全桥仿真分析,主要内容如下：
(1)分析了三跨钢-混组合连续曲线箱梁桥在恒载与双车道对称活载、单车道偏载作用下的结构响应；
(2)分析子上述三跨钢-混组合连续曲线箱梁桥在骤然降温、日照影响两种温度荷载作用下结构的响应；
(3)考察了支承布置形式和横隔扳间距对结构受力性能的影响。
本文得出的一些结论可为公路钢-混组合连续曲线箱梁桥的设计提供一定的参考依据。
The steel-concrete composite curved box girder is a new kind of composite structure, in which the concrete deck slab and the steel box co-act together has come into widely use by western developed countries because it has so many advantages such as big stiffness, low building height, good capability of contradicting shake, quick construction. Along with the development of our country's transportation and the construction of city infrastructure, this type bridge must be widely used in China too. So this thesis proposes to study the structural behavior of a three-span steel-concrete composite curved box girder, it is significant.
This thesis introduces the application and current research of the curved bridge at home and abroad, computational analysis theory about curved bridge, get a preliminary understanding about the stress characteristic and analytical method of curved girder. In order to study the structural behavior of the steel-concrete composite curved box girder bridge, the author uses ANSYS simulate a three-span steel-concrete composite curved box girder bridge. The main contents are follows:
1. Research the structural behavior of the structure under dead load and live load including double-lane symmetry live loads and single-lane offset load.
2. Research the structural behavior of the structure under two different temperature load which can reflect the condition of sudden cooling and sunshine influence.
3. Research the structure mechanical behavior under different supporting forms and spacing of diaphragm.
The results may be taken as reference for the design of steel-concrete composite curved box girder.
