DRIFT ANALYSIS IN MULTISTORIED BUILDING

In Multistoried building design, lateral load ((i.e. wind or earthquake loads) are mainly responsible for drift which very often dictates in selection of structural system for high rid. To bring the maximum drift down to allowable limits, cross sectional of beams and columns have to increase in many case. For buildings having small number of storey, lateral load rarely affect of the building increase, the increase in size of structural members and possible rearrangements of the structure to account for lateral load. The lateral displacement in moment frames is the greatest among the other  lateral load resisting systems investigated; the lateral displacement in dual frames is the least while the lateral displacement in shear wall systems is slightly higher than that of the dual system
