  bnÞkxül Wind Load  Wind Hazard ã Buildings and structures shall be designed and constructed to resist the forces due to wind pressure. ã The forces exerted by the wind are the result of a combination of factors such as:  – Wind speed  – Exposure factor  – Aerodynamic shape of the structure  – Dynamic response factor ã All  structural systems shall be designed and constructed to transfer wind forces to the ground.  Design Wind Loads For rigid buildings of all height P=qGC p    –  q i (GC pi ) Where q=q z  for windward walls evaluated at height Z above the ground. q=q h  for leeward walls, side walls and roofs, evaluated at height h. q i  =q h  for windward walls, side walls, leeward walls, and roofs of enclosed buildings and for negative internal pressure evaluation in partially enclosed buildings. q i  =q z  for positive internal pressure evaluation in partially of the highest opening in the building that could affect the positive internal pressure. G= gust effect factor C p  = external pressure coefficient GC pi  =internal pressure coefficient
