According to the mechanical and deformation characteristics of inverted triangular truss under seismic loads, the calculation model of truss dynamic response is established and the corresponding calculation equations are derived. Making use of finite element software ANSYS, a finite element program of truss dynamic response under seismic loads is made. The finite element analysis model of inverted triangular truss for the cross section of the ground gathering project in PuGuang field is established and the dynamic characteristics of the truss under the seismic loads are simulated by using this program. Finally, the vibration modes and natural frequency of truss can be got. By the time history analysis method, the truss seismic response can be analyzed and the corresponding conclusions can be got. This can provide references for spatial seismic response of large-span inverted triangular truss. |
