Pushover Analysis of a Reinforced Concrete Building According to Various Hinge Models

Abstract

In this study, behavior of a multi-story reinforced concrete frame building designed as three bays and six stories is investigated. Pushover analyses of the selected building are performed according to various lateral load patterns and hinge models. Uniform and inverted triangular shapes are selected for the load patterns while lumped and spread hinge (fiber hinge) models are used for hinge models. Analyses are performed by Sap2000 and Seismostruct programs. Capacity curves and interstory drifts of the building are compared with each other for various lateral load patterns and hinge models, and obtained results are evaluated.
