| Abstract: | Based on the studies of self vibration of flexible support system for point supported glass curtain wall, this paper investigates its wind vibration response with ANSYS.The pulse wind load is determined and the time process curve of pulse wind load by AR method is simulated.The transient analysis of the support system is done with the time process curve.This paper also investigates the influence of concentrative qualities,prestressed tensile force of the cable and rise-to-span ratio of the system on the wind vibration response performance and the wind vibration factor of the system. |
