Now the values in ETABS are inverse so our limit is 0.7x3.5/0.025 = 98. In ETABS the drift is reported as 1/x where x is some number. Now as long as x (some number) is greater than 98 our limit of 0.025 x story ht is being satisfied.

To understand story drift, also known as inter-story drift, we first need to understand story displacement. Story displacement is the deflection of a single story relative to the base or ground level of the structure. Intuitively, we can expect higher total displacement values as we move up the structure. So, a graph … See more Story drift then is the deflection of a single story relative to the previous story. Because the story drift is relative to the nearby levels, we … See more 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 … See more Web• Calculation of wind uplift pressure, base shear forces (wind and seismic), top deflections, inter-story drifts were done and checked according to serviceability state limits. ... • The results were compared for different damping ratio coefficients to understand effects of material and type of construction.
