Story drift limit as per is code

WebThere is a considerable uncertainty regarding the evaluation of the maximum allowable story drift as well as the maximum allowable lateral drift at the top of a building. Various seismic codes suggest values that range from h/50 to h/2000 where h is the height of a building. Web21 Jun 2024 · As stated above, the seismic drift limits are 2% & 2.5% of the story height for long and short -period buildings. So, for a floor to floor height of 12 feet the max. allowable inelastic drift value would be 2% of 12 feet= 0.02*12*12inches=2.88 inches. For wind for a 12 story height, drift would be L/400=12*12/400 =0.36 inches
