Numerical Simulation of Fluid-Structure Interaction for Tension Membrane Structures
Abstract:
Comprehensive studies on effect of fluid-structure interaction and dynamic response for tension structure were conducted by the numerical simulation. An iterative coupling approach for time-dependent fluid-structure interactions is applied to tension membranous structures with large displacements. The coupling method connects a flow-condition-based interpolation element for incompressible fluids with a finite element for geometrically nonlinear problems. A membranous roof with saddle shape exposed to fluctuating wind field at atmosphere boundary layer was investigated for the coupling algorithm. The dynamic response and the fluctuating pressure on member structure were calculated according to the coupling configuration.
