Current records show numbers of building structure component failure due to wind storm. Mostly in the normal practice of design consideration during design stage are only considered on extreme wind speed that probably occurred rarely. However there are also claim that direction of wind and repeatable lower wind from same direction may reduce the strength of the building component. On 2nd June 2009, the roof of the stadium of Kuala Terengganu has been collapsed. In this study one of damaged stadium was investigated due to the effect of wind speed. Computational Fluid Dynamic has been used in order to examine the effect of wind to the stadium. From the result it clearly shows that wind load may increase up to 2.68 times at South East Direction from the normal wind act to the stadium. Historical wind speed also has shown foremost wind blow come from South East direction. The maximum increasing of wind speed are from South East direction. Additionally the data collected from nearest meteorological station show the most frequency of wind come from the South East direction. From the observation the triggering collapse of roof stadium is located on the south east side of the stadium. Therefore the collapse of roof stadium to experience the repeatable wind speed and increasing wind speed due to the direction are remarkably exposed. It can be conclude that the possibility of collapse roof are highly predictable due to wind speed. The effect of the geometrical shape of the structure may also increasing the wind load effect to the building component. Therefore consideration of the geometrical shape and the orientation of the building are vital at the design stage.
