Abstract:In order to promote the green and sustainable development of modern transportation science and technology, the design of valley landscape bridge needs to achieve the goal of environment-friendly innovation. The main bridge of a pedestrian landscape bridge is a cable supported truss structure, and the both ends of the bridge are connected with a tunnel in the mountain. In order to reduce the impact of wind and rain induced vibration in the valley, through the truss of double inclined steel cable-stayed bridge and the pre-installation of steel cable damper, the innovative balance method is used to reasonably deal with the force transmission and transfer at each support, and simplify the support structure. After explaining the formation process of the design concept and introducing the basic information of the bridge, the reasonable static analysis of the bridge and the optimization of the camber are carried out. At the same time, the seismic feasibility of the proposed bridge is checked and calculated from two aspects of response spectrum analysis and time history analysis, which is hoped to be helpful for the design and construction of similar bridges in the future.
