Structural Stability Analysis of Phoenix-Shaped Pipe Truss of Shaohuashan Upper Station Building

Abstract:

Stabilization of steel structure has always been a key concern in the engineering world. 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 finite element method was used to analyze its stability, and the overall structural eigenvalue buckling analysis and nonlinear instability analysis were carried out. It is shown that the factor of safety of the structure is inversely related to the initial defects under the consideration of the influencing factors of the initial defects. The instability modes of the structure are instability of the connecting rods connecting the five groups of tube trusses, instability of the bottom rods of the structure, and instability of the head rods of the skeleton.
