Abstract: Suspend-dome structure form which colligates advantages of cable dome and reticulated shell is a new type spatial hybrid structure system. This article introduced the configuration and principle of suspend-dome structure system, and researched the structural behavior influence by altering the joint stiffness, vector height of the suspend-dome and the loop cable pretension. The results show that suspend-dome structure should make comprehensive consideration on interaction between vector height, prestress application and other factors, and relevant optimizing design method can be adopted in the design.

Abstract: This paper analyzed natural vibration frequencies and vibration modes of suspend-dome structure with finite element method. Firstly, to get the corresponding vibration mode of each frequency of the structure, understand the distribution of directional stiffness in the structure, and realize the basic natural vibration characteristics, this paper analyzed the natural vibration characteristics of suspend-dome structure. And then, this paper analyzed such four parameters as rise, roofing mass, sectional stiffness of the rods, and prestress in the cables. Through comparison of the four parameters, we can get the similarities and differences among their frequencies and vibration modes, and whether or not the mass and the stiffness are harmonious, and draw some valuable conclusions for structural design.
