Overview of Wind-induced Response for Large-span Tension Structures

The analysis of large-span tension structures represents a highly geometrically non-linear problem,whose analytical solution is very difficult to obtain.Moreover the interaction effects between the loading process and the response process have to be considered.This paper first overviews the study on wind-induced vibration for large-span tension structures by means of geometrically non-linear random vibration methods.In the second part of the paper,a simplified aerodynamic model,based on wind tunnel test,was proposed.Finally,the technique of computation fluid dynamics(CFD) was introduced to predict the values of wind forces and wind-induced response by means of numerical simulation.
