Abstract: Abstract of thesis entitled POST-CRACK AND POST-PEAK BEHAVIOR OF REINFORCED CONCRETE MEMBERS BY NONLINEAR FINITE ELEMENT ANALYSIS Submitted by Wu Yi for the degree of Doctor of Philosophy at the University of Hong Kong in September 2006 This thesis investigates the post-crack and post-peak behavior of reinforced concrete members by using finite element analysis. To achieve this, a finite element code with displacement controlled iterative scheme is developed. The finite element code is able to represent the complete load-deflection curve of reinforced concrete member from the initial loading stage till the post-peak stage. Bond-slip interaction between concrete and longitudinal reinforcement is included. To validate the finite element code, experiments of reinforced concrete members with different longitudinal reinforcement, web reinforcement, concrete strength and axial compression are studied. Case studies show that if the bond-slip is neglected in the finite element analysis, the predicted load-deflection curve and crack pattern will give less accuracy. A study of the mesh size-effect of concrete element shows that the mesh should be fine enough in order to give better prediction. By including the bond element and using proper element size, the results show that the proposed finite element code gives a good description of the behavior of reinforced concrete members, including crack patterns and the load-deflection responses. i By using this finite element code, reinforced concrete beams with different concrete grade, steel ratio are studied to investigate the post-crack behavior of reinforced concrete members. The analysis demonstrates that the predicted load will be under-estimated after the concrete has cracked if the tension-stiffening effect is neglected in the section analysis. Based on the results obtained from the finite element analysis, three new concrete stress distribution blocks are proposed. Compared with the current design codes in which the contribution of cracked concrete in tension is simply neglected or other far more complicated methods proposed for the finite element analysis, the tension-stiffening effect can be taken into account in a simple manner in the proposed models for the section analysis of reinforced concrete beams. Several classic reinforced beams are adopted to validate the proposed models. The results show that the proposed models give a good description of the load-deflection behavior of the reinforced concrete members for cracked concrete. In the investigation of the post-peak behavior of reinforced concrete beams, it is found that beyond the ultimate strength, the strain reversal history of longitudinal reinforcement has significant effects on the load-deflection behavior of the member. The predicted load may be over-estimated for an under-reinforced concrete beam when the strain reversal history of longitudinal reinforcement is neglected. It is therefore suggested that the strain history effect should be included for more accurate prediction of the post-peak load-deflection curves of reinforced concrete members. The variation of curvature along the beam length is also investigated. It is shown that the phenomenon of curvature reversal occurs at the post-peak stage for over- reinforced concrete sections in a simply supported beam that is subjected to concen
