Abstract：
Based on the analysis of wind tunnel test on Ji'nan Western Convention and Exhibition Center, wind pressure variation of long-span and high-rise buildings are obtained, respectively. Then results are showed. Due to the separation effect of wind, the wind pressure coefficient under the action of wind load is larger in the edge area of the large span roof, the shape coefficient of building on the roof of middle region is small, therefore, when the roof maintenance structure is wind resistant design, the roof should be reasonably partitioned and different wind resistant measures are applied in different regions; Because the outside of the building glass curtain wall more, the local wind pressure coefficient of high rise buildings under wind load is very large. Therefore, it should be strengthened in the design of glass curtain wall.
