Abstract
To study the effect of roof opening on wind effect of large-span roof structure, wind tunnel tests on a large-span retractable roof were carried out in a boundary layer wind tunnel, then the characteristics of wind loads on the roof were studied, and the wind-induced responses influenced by the opening were investigated in time domain. The results induct that the models for the large-span structure are concentrated, the largest modal energy occurred in first model, and the contributions from higher order are not ignored. The wind loads reduced when the roof with opening, the same tendency was found for wind induced displacement response and acceleration response. The output will be a reference for wind load design of large-span retractable roof.
