Seismic Design of Friction-Damped Precast Concrete Frame Structures
This paper is on the seismic design of unbonded post-tensioned precast concrete frame structures that use friction dampers for supplemental energy dissipation. A procedure is described to determine the friction damper slip force and the area of post-tensioning steel needed in a frame to satisfy prescribed lateral strength and energy dissipation requirements. The proposed design procedure assumes that the lateral strength requirements for the frame have been obtained from a linear elastic analysis of the structure under equivalent lateral forces. Nonlinear reversed cyclic analyses of friction-damped precast concrete beam-column subassemblies and multi-story frame structures under lateral loads are conducted to evaluate the design procedure and to identify areas where improvement may be needed. The analytical results show that friction-damped precast concrete frames can achieve significant energy dissipation levels while maintaining a large level of self-centering capability due to the post-tensioning force.
