The reinforced concrete coupled core wall (CCW) structures have been widely used in the medium to high-rise buildings due to their advantages both in the architectural and structural aspects. The structures not only accommodate the versatile architectural needs, but provide large lateral load resistance to withstand earthquake and wind. The design of CCWs is typically based on the traditional strength-based method, which is the basis of current codes. However, the resulting extremely high shear stresses in coupling beams have been a long-lasting difficulty associated with the use of strength-based methods for seismic design of CCWs. The performance-based design (PBD) method, as a solution to the aforementioned problem, has been recently proposed in an attempt to capture the expected behavior of CCW buildings subjected to ground motions, while producing safe and constructible buildings. In this thesis, a 15-story reinforced CCW office building was initially designed by using the strength-based design method. The resulting high shear stresses in beams exceed the code limits, and no suitable design could be found unless unrealistic measures such as artificial reduction of beam stiffness are used to lower the demands. Subsequently, the PBD method was applied as an alternative to the same building. The coupling beams and wall piers were designed with acceptable internal forces below the code limits. As necessary, the design provisions form NEHRP 2000, ACI 318-02, and FEMA 356 were used. An analytical model was developed to generate the force-deformation characteristics of diagonally reinforced concrete coupling beams. This model was calibrated based on experimental data from previous studies on coupling beams. Using this model and prior experience with modeling of wall piers, a detailed analytical model of the 15-story prototype was conducted. The applicability and validity of the PBD method used in this study were demonstrated through nonlinear static and dynamic analyses of the prototype structure.
