Web17 Jan 2013 · For light-frame buildings, the maximum permitted drift is 2.5% of the story height. This limitation is put in place not merely for serviceability reasons, but is an inherent effect of current seismic design provisions …

When it comes to the limits and allowable story drift, it depends on what kind of force is causing the deflection, with more rigorous limits set for seismic forces. These limits are usually presented either as a ratio or a percentage, but always depend on the story height, usually represented as "h" or "H" For wind loads, … See more To understand story drift, also known as inter-story drift, we first need to understand story displacement.
