Geometrical Non-Linear Analysis of Truss Structures under 3D Seismic Loads
The seismic response of space structures has been widely studied in the past few years. It has been shown that space structures behave well under seismic loading. However there has been little attention given to the effects of geometrical non-linearity on the seismic response. In this paper, a double-layer truss model was created by finite element analysis program-Lusas. The analysis process took into account of geometrical non-linearity and a 3D seismic loading obtained from a real earthquake. Time-history method was used to investigate the axial forces and displacements of critical members of the model during the earthquake. The seismic behavior of the model and the effect of non-linearity were finally discussed for further applications and studies.
