Continuous welded rail (CWR) has been widely applied to the Chinese high-speed railways. It is interesting to reduce the effect of rail longitudinal force on the long-span cable-stayed bridges. Taking the pile-soil interaction into account, the finite element model of CWR on the long-span cable-stayed bridge is established based on the bridge-track interaction theory. The rail longitudinal force can be reduced and the track stability can be improved significantly by installing Rail Expansion Joint (REJ). The layout scheme of REJ plays a controlling role on designing CWR on bridges. Results show that the unidirectional REJ should be laid on both ends of the long-span cable-stayed bridge. Switch rails of REJ are set up on the main beam, stock rails are laid on the simply supported beams and crossing over beam joints, and several-meter long small resistance fasteners need to be laid on the sides of stock rails to reduce the fixed pier longitudinal force near the main beam. The range of REJ laid on cable-stayed bridge is mainly determined by temperature, rail breaking, and seismic condition; the bending and braking loads have little influence on it. Multiple field tests are carried out to prove the validity of the numerical model and the design methodology.

“…As a consequence, the spatial discretization presents difficulties in describing geometric nonlinearities [7][8][9]. Here, a truss model is proposed as an alternative to the usual finite elements [10][11][12]. Thanks to the very simple geometry of a truss, the equilibrium equations can be easily written and the global stiffness matrix can be easily updated with respect to the deformed truss, within each step of static analysis, so that to take into account the strong geometric nonlinearities.…”

In this paper, a truss model is used for the geometrically nonlinear static analysis of a thin shallow arch subject to snap-through. Thanks to the very simple geometry of a truss, the equilibrium conditions can be easily written and the global stiffness matrix can be easily updated with respect to the deformed structure, within each step of the analysis. A very coarse discretization is applied. For the geometrically nonlinear static analysis, a short computer program has been developed by displacement control of a plane truss model of a structure. This very short, fully documented computer program is applied on the geometrically nonlinear static analysis of a specific thin shallow arch subject to snap-through.

“…The temperature design parameter has a close relationship with the geographical position, direction, natural condition, material, and so on of a bridge and is difficult to determine. The temperature parameter is a complex random variable; it plays an important role in determining the stress and deformation of the structure [12][13][14][15][16][17][18][19][20][21][22][23]. This paper analyzes the causes of temperature stress.…”

The temperature is one of the important structural design parameters in the construction control of bridges. The structural stress and deformation are significantly influenced by the temperature. As a complex random variable, the temperature parameter has a close relationship with the structural location, orientation, materials, and the natural conditions, as well as the time variable, and is very difficult to be determined in the construction. In this study, in order to compute the temperature stress from the bridge structures effectively and accurately, the factors affecting the temperature stress are analyzed. The calculation method of the temperature field of the concrete structures is investigated. According to the basic assumption, the calculation formulas of the temperature self-restrained stress and the temperature inferior stress are thoroughly analyzed, and the corresponding calculation formulas are proposed, respectively. Furthermore, based on the proposed calculation models, adopting the fine element numerical simulation method, the influence of the temperature on the bridge structure stress is analyzed and investigated. The research results provide an import theoretical and experimental basis for the construction control of bridges.
