| The objective of this research is to predict the complete behavior up to structural failure of reinforced concrete planar members under cyclic as well as monotonic loading. The structural members to be addressed are beams, columns, beam-column joints, and shear walls, all of which experience damage initiated by tension cracking.; The proposed analytical approach will be able to simulate the behavioral characteristics of reinforced concrete structural members, due to crack opening and closing, compressive crushing, cyclic history of reinforcing steel, and bond-slip between cracked concrete and reinforcing steel.; By simulating the complete range of structural response, the proposed analytical approach can predict behavioral characteristics such as ultimate strength, inelastic deformations, primary crack orientations, and failure mechanisms, all of which are useful for the design and evaluation of reinforced concrete structural members.; To accomplish the objectives noted above, this work includes an investigation of material models for two-dimensional finite element analysis under in-plane cyclic and monotonic loading. Also, several nonlinear solution schemes are investigated to produce a numerically reliable analysis method. The proposed material models and the numerical approach are verified by using previously reported experimental results.; For the material model of cracked concrete based on the concept of smeared cracking, the rotating orthotropic axes model with successive cracking is proposed to complement the existing rotating crack model. In addition to the proposed cracked concrete model, the existing material models of reinforcing steel and bond-slip are implemented in the numerical program. The reinforcing steel model idealizes strain hardening and the Bauschinger effects. The bond-slip model idealizes the bond-deterioration due to cyclic loading. |
