The proposed method allows approximately estimating the inter-story drift ratio, a crucial parameter strongly associated with building damage, its distribution along the building height, and its maximum value location. An equivalent continuous beam model with a rotation at the base, consisting of a combination of a shear beam and a flexural beam, is proposed to achieve this. This model derives closed-form solutions for the building's dynamic characteristics. The lateral deformations along the height of frame buildings subjected to a given earthquake load, particularly the inter-story drift ratio profiles, and the maximum inter-story drift ratio parameter, are investigated. The proposed continuous model requires two dimensionless parameters: the lateral stiffness ratio (& alpha;) and the rotation at the base (& theta;), representing the drift ratio of the first story. For the expression of the lateral stiffness ratio (& alpha;) coefficient, a simple equation is also proposed using the beam-to-column stiffness ratio (& rho;, or Blume coefficient) associated with the framed (discrete) system. Various building models are employed to validate the proposed method, demonstrating its applicability to both high-rise and low-rise building configurations. With the results obtained, it is shown that the proposed continuous model can be used not only for high-rise or multistory building models but also for low-rise building models.eninfo:eu-repo/semantics/openAccessFloor acceleration demandsShearSpectrumStiffnessHeightContinuous beam modelLateral stiffness ratioInter-story driftBlume coefficientEngineeringMaterials sciencePhysicsNATURAL SCIENCES::ChemistryArticle001028431000001131310.3390/app13137819
