The wind pressure distributions over the structure show very complicated feature due to the complex structural configuration and furthermore the interference effects between its main structural members. The basic characteristics of the wind pressures are presented and discussed. Finally, the wind loads for cladding design are computed using the code metbod and statistical approach, which shows that there is a rather big difference between the design wind loads from the two appmaches. Accordingly, a combined consideration of the above mentioned methods should be duly made to provide the safe and proper design loads for the structure.
