“…The stability of the structure to replace the strength has become main factor in the process of design and construction. At present, many scholars have studied in the dynamic stability of single layer reticulated shell structure [4][5][6][7][8] , the frame structure [9] , concrete filled steel tube arch bridge [10] , and high pier continuous rigid frame bridge [11] , but the dynamic stability study of hollow thin-walled high pier is less, which makes the dynamic stability analysis of hollow thin-walled high pier become very necessary.…”

Hollow thin-walled high pier is a common form of high pier in mountainarea, so it is of practical significance to the dynamic stability analysis ofhollow thin-walled high pier in mountain area. This paper is taking themountainous area of a hollow thin-walled high pier as the background, and theestablishment of the fiber model with Midas for dynamic elastic-plastic timehistory analysis. The results show that: the hollow thin-walled high pier underthe impact load, load amplitude is lower than the critical load,and the dynamic response characteristics of thestructure of the value parameter i.e. horizontal displacement at pier top increaseslinearly with the load amplitude. When the load amplitude is larger than thecritical load, the horizontal displacement of pier top increases with theincrease of load amplitude nonlinearly. Power under dynamic load instabilitycritical load is about 80% under static load.

This paper first used parametric design language APDL to establish three kind of the single hyperbolic paraboloid shell model with rectangular projection. The parametric design of the reticulated shell structure could be realized after inputting the span (S),rise (F),the grid number of each side (Kn),the warping rate (K),which provided great convenience for optimizing the structure and force analysis.Then through contrasting three structure schemes and different warping rate,it studied how they influence the mechanical properties of structure.And at last it got some conclusions with engineering significance.
