NONLINEAR SIMULATION OF AIR-SUPPORTED STRUCTURES

Abstract

Technique of the nonlinear numerical analysisof the air-supported structures including fluid-structural interaction (FSI) has been described in the present paper. Numerical simula- tion of the tunnel test of large-scale air-supported model has been carried out as example of using this technique. The comparison of the experimental and numerical resultsdemonstrated applicability of proposed technique to the considered class of problems. Opportunity to de- velop this technique to the more complicated and advanced problems has been shown, too.
