Effect of Aspect Ratio on Response Reduction Factor of RC Building

The behaviour of a building during earthquakes depends on its overall size, shape and geometry. The building aspect ratio is the key factor for the efficient structural design. This research emphases on the effect of both plan aspect ratio (L/B ratio i.e. horizontal aspect ratio) and vertical aspect ratio (H/B ratio i.e. slenderness ratio), where L is the length of the building frame, B is the base width & H is the total height of the building frame. Here, height and the base dimension of the building are varied according to the aspect ratio and calculate the actual value of response reduction factor for SMRF frame and comparing these values with the value suggested in IS 1893.
