| Abstract | The article presents a study on the seismic behaviors of different categories of fully slitted shear walls which was supported by the National Science Council of the Republic of China and supervised by the authors. Two analytical models of lateral stiffness for a fully slitted RC shear wall are presented. Seventeen specimens divided into three categories, including five one-story walls without boundary columns, eight one-story walls with boundary columns, and four two-story walls with boundary columns are investigated. Four types of lateral loads (monotonic loading, repeated loading, reversed cyclic loading, and random cyclic loading) with or without axial force are applied in the study. The column model and the truss model are employed for analysis. The comparison of analytical and experimental results shows that most of the flexural cracking load, yielding load, and ultimate load for one-story specimens predicted by the column model are lower than those of experimental results. However, most of the predicted values for two-story specimens are higher than those of the experimentals. The errors in the analytical ultimate load are found to be between 2.7% and 9.0% for the column model, and between 3.0% and 7.8% for the truss model. In addition, the comparison of load-deflection curves for both models shows that the predicted lateral stiffness has satisfactory accuracy. |
