There are few studies on the installation of appropriate cambers for long-span railway cable-stayed bridges at home and abroad. This article describes the influential factors of thte installation of cambers, and analyses its theories and approaches, as well as takes use of design formula for appropriate camber installation. Combining project cases of long-span railway cable-stayed bridges, and exploiting FEM software-Midas civil2010, the article has an analytic study on effects of different construction processes on camber installation, which is the basis of installing cambers of such bridges in the future.

“…Cast-in-place cantilever method is often used during construction of long-span railway cable-stayed bridges, whose procedures are quite complex (Housner et al, 1999;Wang, Tang, & Zheng, 2004;Ge, 2003). Establish a reasonable state of a finished bridge, and then it follows the construction state which is based on the outlined construction processes.…”

Cable force of construction control and alignment control of main girders are key factors for long-span railway cable-stayed bridges. To make both stayed cable force and alignment of main girders under ideal state simultaneously during construction, based on first-order optimum algorithm, this article regards bending strain energy as an objective function, and then the initial tension can be known through iteration. After analyzing the impact of some factors on alignment control of main girders, such as initial tension of stayed cables and construction load, the formula of alignment control about main girders can be obtained. Finally, taking one of the world's largest railway cable-stayed bridges for an example, the article calculates the initial tension of stayed cables, and analyses the effects of some factors on alignment control of long-span railway cable-stayed bridges. It turns out that this method can keep the alignment and internal force of main girders reasonable.Keywords: cable force of construction control, alignment control of main girders, first-order optimum algorithm, initial tension of stayed cables

“…The shape finding computation is performed using a two-loop iteration method: an equilibrium iteration and a shape iteration [18][19][20][21][22][23]. It can be started with an estimated initial element force (pretension force) in the stay cables.…”

“…This is because such initial shape not only reasonably provides the geometric configuration as well as the prestress distribution of the bridge under the weight of the deck-tower system and the pretension forces in the stay cables, but also definitely ensures the satisfaction of the relations for the equilibrium conditions, boundary conditions and architectural design requirements [18][19][20][21]. The computational procedures for the initial shape analyses of the OECS and MECS models were presented for this reason [22,23].…”
