1.1. This structural calculation is executed for the cross section of SECTION SLAT 6-11 to find out the safety against the wind load. When the only cross section of the slat is not secure against allowable stress limit, the support post will be reinforced to ensure the structural safety. 1.2 The type of wind load is for the wall components and cladding. (enclosed bldg.) 1.3 This design considered both windward&leeward wind loads. 1.4 Structure safety check of existing
