Numerical Investigation of Seismic Performance of Reinforced Concrete Frame Strengthened With CFRP

Reinforced concrete (RC) structure performance behavior investigation is important in order to produce structural systems having stiffness, strength, deformation capacity required to withstand seismic loading with acceptable performance. Number of studies conducted to investigate the performance of structural RC frame members such as beams, columns, beam-column joints under seismic loading, primarily using experimental methods. The main aim of this thesis is to investigate numerically the performance of RC portal frame strengthened with 0%, 10%, 15%, 20%, 25% and 30% of total length of RC frames with carbon fiber reinforced polymer (CFRP) under seismic loading in displacement control. In the first scheme of this study finite element model for six RC portal frames strengthened with different percentages of CFRP have been developed by using finite element software called ABAQUS and those RC portal frames with identical dimension of beam and columns of cross section of 300x350mm and column is 1365mm in height and beam of 2350mm length has been simulated under seismic loads up to 3% drift ratio in displacement control. In the second schemes of this study finite element model for three RC portal frames (one as base lines and two were strengthened with CFRP sheets) subjected to lateral cyclic load and gravity loads on beam critical zones. Nonlinear finite element analysis with damaged plasticity model for concrete and orthographic elastic properties for CFRP in ABAQUS/standard is adapted to simulate RC portal frames. The accuracy of the nonlinear finite element models has been verified using the experiment results conducted on beam-column joints by other researchers. The Finite Element Analysis (FEA) results showed that strengthening the RC portal frame with the 10%, 15%, 20%, 25% and 30% of CFRP increased the dissipation energy capacity by 2.39%, 4.1%, 5.95%, 7.04% and 7.39% respectively. Results also showed that strengthening with CFRP results in fewer cracks, less degradation of strength after yielding than bare RC frame and decrease in stiffness degradation.
