The height of tower is 330m. The characteristic value of wind load calculated according to the ?Load Code for the Design of Building Structures GB50009-2001? is 4.1 KPa, while per the wind tunnel test provided by Owner, the Max wind load is on the L26 of the eastern fa?ade, 110.6m high, whose characteristic value for the wind load is 3.3 KPa Therefore 4.1KPa is adopted when conducting the structural calculation for the hotel floor. 玻璃翼风荷载按照风洞试验报告最大值选取，其风荷载标准值为8.25 KPa。 the Max value 8.25 KPa of wind tunnel test is adopted for the wind load on glass fins.
