    • In this study, Non-Linear Static behavior of High strength concrete (HSC) columns and beams reinforced with High strength reinforcement is investigated (HSR). A database of 88 cyclic test on specimen’s representative of HSC and HSR (beams and columns) was analyzed. Analysis were performed using ETABS, TEASPA and FEMA P695 documentation and compared with experimental results. This study aims to investigate the capacity of different models to reproduce the nonlinear behavior of high strength concrete framed structures (Beams and Columns) reinforced with high strength reinforcement. However, the results from analysis was not satisfactory hence, two different approaches were proposed. In this study also the experimental procedure for five HSC NEWRC columns and one NEWRC Frame structure reinforced with HSR are discussed. The experimental results obtained from NEWRC Frame structure is used for verification of the proposed model. The results from proposed model were highly accurate. Therefore as outcome of this research, modeling parameters and numerical acceptance criteria for high strength reinforced concrete beams and columns are presented helping the users to choose the best approach to perform nonlinear analysis.
