A plastic hinge, in structural engineering, refers to the deformation of a part of a beam wherever plastic bending happens. Hinge means that having no capability to resist moment. Therefore, a plastic hinge behaves like a standard hinge - permitting free rotation. The main result of a pushover analysis, consists of the “capacity curve” representing the displacement of a selected control point, generally assumed coincident with the center of mass of the top floor of the building, versus the base shear coefficient (Cb). . pushover qura The nature of loading governs the kind of analysis to be performed on the structure. The loads are divided into two basic categories Static Loads are the loads which varies very slowly (the acceleration of load is very very less than the natural frequency of the structure) Dynamic Loads are the loads which changes with time fairly quickly in comparison to the structure's natural frequency. Pushover Equivalent Static Analysis Pushover analysis is a sta...
