Dynamic Stability Analysis of Single-Layer Lattice Dome Considering Member Imperfections

Abstract:

Dynamic stability analysis is a very important research project in the space structures. Up to now, in most researches, the imperfections of members are not included in the dynamic stability analysis for the single-layer lattice domes. In this paper, using multiple-beam method to simulate the initial bending deformation of the members, the dynamic stability behavior of a Kiewitt-8 single-layer lattice dome under three dimensional earthquake actions is analyzed by considering the member imperfections and the initial geometrical imperfections. The influence of member imperfections to the dynamic stability behavior of the structure is investigated.
