Geometric Construction and Static Analysis on Timber-Arched Structural System of Shouning Timber-Arched Lounge Bridge

Abstract

Abstract Due to the disrepair, many timber-arched lounge bridges have structural safety hazards and require protection. This paper analyzed the structural composition as well as the composition principle of of Shouning timber-arched lounge bridge. It is found that the timber-arched bridge structure belongs to highly indeterminate. The ANSYS finite element simulation analysis of timber-arched lounge bridge shows that three-node and five-node seedlings are the components which are mainly subjected to axial force. Their shear stress is only 12% of the axial stress. Three-node and five-node seedlings make full use of the tensile and compressive properties of wood. At the same time, the portal framed bent, horse leg also play an important part in the structure. The double bridging is the important component to guarantee the wind resistance, earthquake resistance and transverse stability of bridges. The results of this paper have academic guidance meaning for the maintenance and reinforcement of timber-arched lounge bridge.
