Seismic Behavior of Concrete Buildings Using A Controlled Rocking Walls
Mohammad Afshari, Gholamhossein Jafari
Pages: 12-22


These days buildings are designed to support life safety performance level. Widespread damage caused by severe earthquakes due to permanent displacements in buildings, requires a great deal of time and effort to rebuild and rehabilitate these buildings. low damage systems classified in the category of inactive control systems are responsible for controlling permanent displacements and distribution of faults in the structure. In these systems, with the help of energy dissipation systems and pre-stressed cables, it is attempted to direct the damages to predetermined locations in the structure. In this paper, the seismic performance of different systems with rocking shear walls using pre-tensioned cables and dampers in the structure is examined with the view of improving the existing structure, and their performance is compared to the conventional use of fixed shear walls. By Using nonlinear dynamics analysis, we will examine various parameters in a two-dimensional frame with rocking systems. The results obtained in this study indicate that rocking systems are better suited rather than conventional systems used in terms of performance and other important parameters in structural responses and can be used as an alternative retrofit scheme.
