Abstract
A large part of Turkey's urban region is located in the seismic prone zone and in terms of population, the majority of densely populated cities are located close to near-fault regions. It is very important to determine the behaviors of structures against external forces after destructive earthquakes. Structural and non-structural damages that occur during the earthquake usually arise from lateral displacements occurring in the structural system. This is why, in recent years, the displacement-based design has become more important when compared to the force based design. In this study, the Direct Displacement Based Design method under earthquake forces are explained. The process steps of this method on a frame-wall structure are clarified. The dynamic behavior of a moment resistant structures and a combined system with shear walls are compared. The finite element method used to analysis of reinforced concrete building models. Some model with moderate and high vibration period is adopted for dynamic analysis. An arrangement of the shear walls is changed in story plan of models. The dynamic analysis has shown quite different response among the structural systems. The difference in dynamic behavior is coming from the interaction of dynamic response between shear walls and moment resistant frames. Furthermore, the important role of shear walls displacements in transferring lateral loads is clarified with numerical examples. The positive role of RC shear walls on the combined structures under earthquake forces has been emphasized.
