Paper Title:
Vibration Modes Coupling Effect in the Wind-Induced Response of a Ribbon-Like Long Span Roof
  Abstract

The test conditions and main results of wind tunnel test for an exhibition hall and a stadium ribbon-like long span roof of a Sports Convention Center are introduced. We got the average and fluctuating wind pressures of the roof. Then we use typical points measuring method to analyze them. According to the energy contribution method, dominant modes are identified, and the modes response energy is calculated. The coupling coefficient between background displacement response and resonant displacement response is presented in this paper. The stadium calculation mode are Analyzed. The results show that the coupling coefficient numerical range for the ribbon-like long span roof is larger than single-layer spherical shell. When we use energy contribution method to select vibration modes in calculating ribbon-like structure response, Error range is large if the coupling effect is ignored, and some compensatory modes need to be found.
