Analysis of wind resistance for a lightweight steel roof
After the typhoon,the color steel sheet on the lightweight steel roof of a sports hall was partially destroyed.Some components were selected on site for cross-sectional size review,and the mechanical properties of the color steel sheet were tested.The bearing capac-ity of the color steel sheet was analyzed and compared under two working conditions:the reference wind pressure and the actual wind pres-sure of the typhoon.The verification results showed that the bearing capacity of the color steel sheet met the specification requirements un-der the reference wind pressure.Under the influence of an ultra-strong typhoon,the instantaneous wind pressure may exceed the reference wind pressure,and the bearing capacity of the color steel sheet in the edge area did not meet the specification requirements.Based on on-site inspection and verification results,the possible causes of local damage to the lightweight steel roof were analyzed,and a repair plan was proposed.
