Modal Analysis of Tensioned Membrane Structure of Umbrella-Shaped

The tensioned membrane structure is a typical flexible architecture and is sensitive on the wind loads . We used software ANSYS to do modal analysis of the umbrella-shaped membrane structure and analyzed the natural vibration characteristics. We focused on the effect of design parameters on structural modal. The results show that the natural frequency of umbrella-shaped membrane structure mainly depends on membrane prestress and membrane tension stiffness.
