Abstract: Structures encounter lateral deflections under earthquake loads. Extent of these parallel lateral deflections is identified with numerous factors, for example, auxiliary framework, mass of the structure, stiffness modifiers and mechanical properties of the basic materials. Structures should be designed such that they can resist seismic tremor and wind gust effects actuated deflections and internal forces. Structural stiffness modifiers are important factors which gives the behaviour of structure after cracking due seismic or wind forces on the structures. Structures which have auxiliary abnormalities may encounter distinctive floats of drifts of adjacent stories, excessive torsion, and so forth as indicated by inconsistency compose and come up short amid a seismic tremor. In this study, impacts of Stiffness Modifiers on structures, drifts, displacement, modal mass participation, time period, frequency are examined. Building models, which have same number of floors with different stiffness modifiers as per codal provision of IS 16700-2017 are produced by a FEM PC program and calculations are made. Results are compared and safeguards are given with avoid harms caused by Stiffness Modifiers under seismic tremor loads are analyzed.
