Finite Element Analysis of FRP Pedestrian Truss Bridge Mechanic Performance

Under the background of the truss bridge in Gaoliang ship lock across Huaihe river, which is made of glass fiber reinforced polymer (GFRP) profiles, APDL language based on ANSYS is used to organize corresponding command stream program and built 3D finite element model. According to the actual situation of the bridge, the static analysis and modal analysis of the truss bridge to test the static and dynamic performance is conducted. The mechanical property when the bridge material was replaced with BFRP and CFRP is analyzed.
