Nonlinear Response of RC Frames using Plastic Hinge Model

Abstract

Lumped plasticity hinges are popularly employed in many software packages due to easy implementation and simplicity of the computational models. The present study is an attempt to implement a concentrated plasticity hinge model to simulate the nonlinear behavior of RC frame and to perform a probabilistic analysis. The model introduced by Monfortoon and Wu (1962) is implemented in MATLAB 2012 and a probabilistic analysis is carried out by considering the uncertainty in the modeling and geometry parameters to obtain the uncertainty in the responses
