“…The self-anchored suspension bridges do not require huge earth-based anchors and can begenerally used as a feasible solution to cross the channel restricted by terrain and geology; sometimes, self-anchored suspension bridges have become the landmarks for many places (Li and Jia 2005;Xu et al 2016;Zhang et al 2013). The main cables of the self-anchored suspension bridges are anchored at both ends of stiffening girder, which carry the horizontal force resulting from the tensioned cable (Jung et al 2015;Ochsendorf 1999).…”

The traditional construction methods (e.g., erecting cable after girder) of self-anchored suspension bridge, can interrupt traffic during the construction stage due to the installation of temporary supports. That severely limits the wide application of this type of bridges. Thus, this study proposes a novel tower-girder anchorage (TGA) technique for accelerated construction of self-anchored suspension bridges. By using the proposed TGA technique, the mid-span girder segments are hoisted and connected to the hangers, which subsequently avoids the interruption of traffic during the construction period. The proposed TGA technique would reduce the construction cost, time of erection, and demolition of temporary scaffolds.To ensure structural safety and performance during the proposed construction process, the force transfer mechanism and construction process of TGA technique are assessed. To this end, the devices for TGA and system transformation are designed. The constructability of TGA technique on accelerated bridge construction is evaluated by a real-world application: Dongtiao River Bridge in China. A finite element model is established to analyze the construction process. Simulation analysis and field test data are compared. The comparison demonstrates that TGA technique can safely and economically achieve accelerated construction of self-anchored suspension bridges.

“…For instance, the Yongjong Grand Bridge in Korea (Gil and Choi 2001;Gil and Choi 2002;Kim et al 2002;Kim et al 2006) and the new San Francisco-Oakland Bay Bridge in the United States (Sun et al 2002;Sun et al 2004) belongs to this type of bridge structure. In addition, this type of bridge has also been adopted in China, and many bridges of this type have been constructed, such as the Fumin Bridge in Tianjin (Sun et al 2015;Xiong et al 2017), the Qingdao Bay Bridge (Nie et al 2011), the Liede Bridge in Guangzhou (Zhang et al 2013), the Jiangdong Bridge in Hangzhou (Li et al 2010;Zhang et al 2010), the Jiangxinzhou Bridge in Nanjing (Li et al 2013), and the Tianhe Bridge in Songyuan (CSCEC-6th-Bureau 2016; Huang et al 2017;MingHao-technology 2016).…”

Configuration transformation is an important issue during the construction stage of spatial suspension bridges with three-dimensional (3D) curved cables. Without fully considering this issue, the hangers could collide with the cable duct at the connection of the cable and girder, which can cause damage to the hangers and hamper the construction procedure. This paper proposes a novel technique using lateral bracing members (LBMs) to aid the configuration transformation during the construction stage of suspension bridges. The lateral displacement and rotation angle are investigated to ensure safety during the construction process. The limitations of the conventional configuration transformation techniques are acknowledged. In order to demonstrate its capability the proposed technique is applied to a suspension bridge ,the Dongtiao River Bridge, located in Huzhou, China. Based on the results, it can be concluded that the LBMs can provide an efficient, reliable, and economical solution to aid configuration transformation of 3D curved cables of suspension bridges during the construction stage.

“…This paper explores how to move the main girder away from a supported state and studies the optimization method of the stretching frequency and the number of prolonged rods. Based on the experimental data from a 1 = 10 scaled model of the Liede Bridge in Guangzhou, China, Zhang et al (2013) studied the nonlinear behavior of a self-anchored suspension bridge during the process of structural system transformation. Jianhua et al (2007) based his research on the internal force equilibrium method, and studied the hanger forces of a completed self-anchored suspension bridge.…”

Purpose The purpose of this paper is to develop a simplified optimization calculation method to assess cable force of self-anchored suspension bridge based on optimization theories. Design/methodology/approach A simplified analysis method construction using Matlab is developed, which is then compared with the optimization method that considers the main cable’s geometric nonlinearity with software ANSYS in an actual bridge calculation. Findings This contrast proves the weak coherence and the adjacently interaction theory unreasonable and its limitation. Originality/value This paper analyzes the calculation method to assess cable force of a self-anchored suspension bridge and its application effect.
