Wind Load Analysis Concept of Wind Load Analysis: Buildings are subject to horizontal loads due due to wind pressure acting on the buildings. Wind load is calculated as per IS !"#$art III%&'(!. )he horizontal wind pressures act on *ertical e+ternal walls and e+posed area of the buildings. So,e of the pressure acting on e+posed surfaces of structural walls and colu,ns is directly resisted by bending of these ,e,bers. )he infill walls act as *ertical plate supported at top and botto, by floor bea,s- thus transferring the loads at slab le*el. )he parapet wall is at terrace transfers the wind loads to the surface slab by cantile*er action. or si,plicitythe wind loads acting on e+posed surfaces of a gi*en storey are idealized to be supported by upper and lower floors. Wind load analysis as per IS 875 (Part 3)-1987 : Wind forces acting on a gi*en surface is e/ual to the wind pressures ,ultiplied by the effected area.
