主　　题：arc-shaped canopy roof numerical wind tunnel method wind pressure coefficient wind tunnel test skylights 

摘      要：In this paper,the wind load on an arc-shaped canopy roof was studied with numerical wind tunnel method(NWTM) .Three-dimensional models were set up for the canopy roof with opened or closed *** air flow around the roof under wind action from three directions was analysed *** pressure coefficients on the canopy roof were determined by *** results of NWTM agreed well with those of wind tunnel test for the roof with opened skylights,which verified the applicability and rationality of *** effect of the closure of skylights was then investigated with *** was concluded that the closure of the skylights may increase the wind suction on the top surface of the roof greatly and should be considered in the structure design of the canopy roof.
