WebFor masonry buildings with cantilevered shear walls, the IBC limits the story drift to 0.01h sx, where h sx is the height of the story below the level for which the drift is being calculated. For other types of masonry shear wall … 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
