Study of the plastic-hinge analysis of 3D steel frames applying nonlinear static analysis

Abstract

This paper provides a distinct study on the performance of different residential buildings with different height and length spans under the influence of applied loads according to the Turkish standard TS498. The research paper presents the nonlinear performance of the buildings and provides a clear picture of the plastic and its stages throughout the construction. The study explains the effect of the various stages of plastic and how it affects the rigidity of the building. The results portray the building's stiffness values and how they change. The results show that stiffness increases with length-increase and decreases by decreasing the height of buildings. All stiffness values were calculated according to the first plastic hinge formation. Software used is ETABS 2018 and all calculations and parameters used according to FEMA356-2000, ASCE 7-16, ACI-318, EURO code 8, and Turkish standard.
