This paper aims to provide guidelines for the numerical modeling of reinforced concrete (RC) frame elements in order\nto assess the seismic performance of structures. Several types of numerical models RC frame elements are available in nonlinear\nstructural analysis packages. Since these numerical models are formulated based on different assumption and theories, the models\naccuracy, computing time, and applicability vary, which poses a great difficulty to practicing engineering and limits their confidence\nin the analysis resultants. In this study, the applicability of four representative numerical models of RC frame elements is\nevaluated through comparison with experimental results of four-storey bare frame available from European Laboratory for\nStructural Assessment. The accuracy of a numerical model is evaluated according to the top displacement, interstorey drift,\nMaximum storey shear, damage pattern and energy dissipation capacity of the frame structure. The results obtained allow a better\nunderstanding of the characteristics and potentialities of all procedures, helping the user to choose the best approach to perform\nnonlinear analysis.
