Control of Extreme Loads on Structures Using Membrane Vibrations
Publication: Journal of Engineering Mechanics
Volume 141, Issue 4
Abstract
The use of a membrane to mitigate the extreme pressure loads on the roof of a surface-mounted prism is investigated. The fluid-structure interaction problem is solved by coupling the unsteady Navier-Stokes equation with the membrane equation. The minimum number of membrane modes required for the solution is determined through a convergence study. The results show that this passive control technique can be used to reduce the extreme pressure coefficients by approximately 25%. This reduction is explained by investigating the effects of the membrane on the flow field.
