Abstract : In this thesis, finite element analysis are performed on the cracking distribution and evolution reinforced concrete walls by using ANSYS program. Reinforced concrete walls are analyzed by incorporating the element models, material models and virtual models. The link model and solid model were used to simulated reinforced steel bar and concrete respectively. In terms of the stress-stain relationship of reinforced steel bar and concrete to establish the nonlinear material models with multilinear isotropic law. Virtual models are created based on the dimensions of the RC walls and integrated with element models and material models to performed finite element models. Four traditional reinforced concrete walls with horizontal and vertical steel bars, two of these traditional RC walls are high-rise and other two are mid-rize, and one new RC wall was used also. These RC walls analyzed with finite element method to obtain the cracking distribution and evolution of RC walls. The analytical results of the RC walls showed the cracking distribution and evolution approximated to the experimental results, and the errors of ultimate lateral force are averaged about 4.68 %. In this thesis, cracking distribution and evolution of RC walls can be predicted with finite element method with ANSYS program.
