Abstract

The paper describes explicit time-integration numerical procedures for the analysis of prestressed membrane subject to dynamic loadings. The analysis accounts for the special properties of coated fabric membranes relating to dominant weave directions, on/off slackening, and visco-elastic material damping. Internal air effects which give rise to pneumatic stiffening, damping and added mass effects are included. External wind loading (limiting to smoothly shape low rise-span structures with low air turbulence) is simulated numerically assuming three dimensional potential flow using the vortex-lattice method.

Physical model tests, in a boundary layer wind tunnel, to examine the pressure distributions on smooth elliptic paraboloid and impulse load tests on large scale air supported fabric membrane dome have been carried out. The results for both series of tests are correlated with the numerically predicted behaviour.
