ANALYSIS OF CONCRETE MATERIAL MODELS

The response of a reinforced concrete structure is determined in part by the material response of the plain concrete of which it is composed. Thus, analysis and prediction of structural response to static or dynamic loading requires prediction of concrete response to variable load histories. This paper presents the concrete material model used in this investigation for finite element analysis of reinforced concrete beam-column connections. the experimental data considered in model development and calibration, and also presents several concrete material models that are typical of those proposed in previous investigations, besides , discusses the material model implemented in this study and a comparison of observed and predicted concrete behavior for plain concrete laboratory specimens subjected to several different load histories
