Study on the Response of Steel Moment Resisting Frame with Vertical Setback Subjected to Lateral Loads

In the present works “ A study on response of steel moment resisting frame (SMRF) with vertical set back subjected to lateral loads� I consider steel moment resisting frame of 15, 10, 5 storied regular 3-D framed of 3 models and 15, 10, 5 storied setback building of 9 models that is 3 of 15, 10, 5 storey are symmetrically in elevation configuration thought its height And 3of 15 storey are setback at 12th, (8th and 12th),(4th,8th ,12th and 15th)storey level and 3 of 10 storey are setback at 7th,(5th and 8th ),(3rd,3rd ,6thand 9th)storey level and 3 of 5 storey are setback at 4th,(3rd and 4th ),(2nd,3rd,4thand 5th)storey level. it is focused to study their response or structural behavior under Equivalent static Analysis and Dynamic analyses in this Time History Analyses with various soil types and various seismic zones of India as per Is-1893-2000 . In the analyses we concluded that the steel moment resisting regular frame models of 15, 10, 5 stories regular and irregular base models. storey displacement or lateral displacement, storey drift, and base shear of regular steel moment resisting frame models are compared to the irregular vertically setback steel moment resisting frames based on graphs which are plotted from tabulated values after analyses. For the modeling analyses ETABS Ver 2013 software is used. The peck value of acceleration and lateral displacement is determined by Time History Analysis for all regular and irregular vertically set back steel moment resisting frames base models.
