The modern building has resulted in the usage of post-tensioning technology in many commercial and residential constructions. Looking at the defects of the usual technique of building, post-tensioning as an upgrade may overcome the inadequacies of the conventional method of construction, such as more thin structural components, lower weight, and smaller floor-to-floor heights. Post-tensioning ensures that every design is both cost-effective and safe. A Symmetrical arrangement of multi-story floors will be considered in this comparative analysis considering Pushover Analysis according to I.S. 1893-2016. The analytical tool ETabs structural programming will be used for the analysis of the case study on the parameters namely parable drift, maximum lateral displacement, story shear, target displacement, and performance point. The Analysis results will be used to study the stability of the Post-tensioned Structure as far as resisting seismic forces against the corners of the structure.
Keywords: Pushover Analysis, Maximum story displacement, Post Tensioning Cables, Target Displacement, Story drift, Stability, Performance point.
