Inter-story drift ratio
Webcodified inter-storey drift limits for buildings are reviewed and seismic drift assessment ... commercial, and residential building types used drift ratio in the order of 0.002H to 0.0025H for steel framed buildings. The Australian Standard “Glass in buildings-Selection and installation” AS 1288 (2 006), WebMaximum Residual Inter-story Drift Ratio (RIDRmax) plays an important role to specify the state of a structure after severe earthquake and the possibility of repairing the structure. Therefore, it is necessary to predict the RIDRmax of Steel Moment-Resisting Frames (SMRFs) with high reliability by employing powerful Intensity Measures (IMs).

WebMay 11, 2016 · The scheme requires only measured inter-story drift displacements without any additional finite element analysis. A method for estimating yield drift deformation is proposed, and then, the degree of beam end damage is evaluated based on the plastic deformation ratios derived with the yield drift deformation values estimated by the … WebJun 21, 2024 · If our limit is 0.025 then the limit we get is 0.025/R/0.7. Assume R=3.5. 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.
