| Abstract: | Wind-induced interaction of wind-sensitive spatial structures is prominent due to their lightweight,higher flexibility and lower damping.Investigation on wind-induced interaction of spatial structures in last decades was clarified and analyzed,including the simplified method,wind tunnel test and field measurement method.Furthermore,numerical simulation based on CFD technique was heavily mentioned,including how to deal with mechanical modeling of structural system,fluid field and grid system,numerical discretization technique and solution strategy,turbulence models and their characteristics,grid generation and updating as well as information transfer and exchange on interface of flow and structures and so on. |

| Keywords: | wind-sensitive spatial structure wind-induced interaction wind load |
