Research On The Wind-induced Vibration Of Cable-membrane Structure

Research on the wind-induced vibration of cable-membrane structure has been done in this paper. First of all, nonlinear finite element formulation for the design of cable-membrane structure is presented. The form-finding and static behavior of the structure are analyzed afterwards. Wind-induced vibration of cable-membrane structure mainly refers to the wind-induced dynamic behaviors of the structure, i.e. the nonlinear behaviors and random responses caused by wind. AR model in linear filter theory is adopted to simulate pulsant wind. Combined with some typical cable-membrane structures, research on self-vibration of the structure has been conducted. Based on the previous work, the influence caused by the vertical wind component on the membrane roofs has been analyzed in time domain. It includes the vibration laws of the structure under separate horizontal wind component, separate vertical wind component and the collective horizontal wind component and vertical wind component. Significant conclusions have been drawn from the analysis. Finally, considering structure-wind coupling interaction, research on buffeting response of cable-membrane structure is done. Rules of buffeting response of cable-membrane structure have been found after analyzing the results.
