Abstract

During the last decades, many researchers have proposed a number of constitutive models for simulating the behavior of reinforced concrete structures under cyclic loading. The finite element analysis, has been used in the past, produce solutions to specific structural members that undergoing different loading conditions. The purpose of this paper is to propose a computationally efficient numerical method in order to simulate accurately the behavior of a wide range of reinforced concrete structural members under cyclic loading. The proposed method is based on the experimental results and the concrete modelling of Kotsovos and Pavlovic [1995] as modified by Markou and Papadrakakis [2013]. An algorithm that describes the development of microcracking, macrocracking and the brittle behavior of the concrete under cyclic behavior, is presented. The concrete domain is simulated by 8- and 20-noded hexahedral elements, which treat cracking with the smeared crack approach. Steel reinforcement is modeled with truss and beam elements which are considered embedded inside the hexahedral concrete mesh. The numerical accuracy of the proposed method is demonstrated by comparing the numerically predicted force-deflection curves with the corresponding experimental results found in the literature.
