Description
Summary:A simple displacement-based methodology is presented in this study for the seismic retrofitting of medium height non-ductile concrete frames. Deformation capacities of the existing columns control design. A minimum amount of infill shear walls are added in both orthogonal directions for maintaining the deformation levels below the level dictated by the existing columns, which are usually at the ground story. Interstory drifts and member end rotations are employed as performance parameters. The proposed displacement based approach has been implemented to school buildings which require higher seismic performance compared to ordinary buildings.
