Seismic Response Analysis of Phoenix-Shaped Tube Truss Structure of Shaohuashan Upper Station Building

Abstract:

Tube truss structures are often used in large public buildings, and their safety performance under seismic effects is very important. The phoenix shape of the upper station house in the ropeway project of Shaohuashan National Forest Park in Shaanxi Province consists of 5 groups of tube truss structures forming an overall space tube truss structure form through connecting rods. The seismic response of this structure was analysed using the vibration mode decomposition response spectrum method. The results show that the overall structural vibration displacement changes in the first 10 vibration modes are concentrated in the head and the tail of each group of pipe truss structures; the internal force and displacement responses of the structure under seven different scenarios of multiple earthquakes are calculated, and the results show that the dynamic response of the structure is the largest under the unidirectional (X-direction) seismic action. The internal forces and displacements of structures under rare earthquakes are multiplicatively related to those under multiple earthquakes, and are closely related only to the coefficient of seismic influence.
