Abstract:
The numerical modeling of the contact problems is applied to the stability analysis of the sheet-spatial structure. Based on the numerical calculations and analysis of the interactive problem, the influences of the contact stiffness and contact status between the sheet and the skeleton on the stability of the sheet structure were analyzed thoroughly. The scope of contact stiffness and setting principle of contact elements were suggested. The computational results were also compared with the experimental data. It is shown that the calculated results and experiment results agree well, and the numerical modeling proposed is reasonable and reliable in dealing with the stability analysis of the sheet-spatial structure based on the actual interaction conditions between the sheet and the skeleton. However the results of completed compatibility of displacement modeling are higher than experiment results, which is not fit for the design.
