Performance-based Design of RC Coupled Wall High-rise Buildings with Viscoelastic Coupling Dampers

A new damping technology, the Viscoelastic Coupling Damper (VCD), has been developed at the University of Toronto for reinforc ed concrete (RC) coupled wall high-rise buildings. These dampers are introduced in place of coupling beams to provide distributed supplemental damping in all lateral modes of vibrat on. This thesis presents an analytical investigation of the application of VCDs in a highrise case study building located in a region of high seismicity. A parametric study has been conduc ted to determine the optimal number and placement of the dampers to achieve enhanced seismi c performance without compromising the wind response of the structure. Nonlinear time hist ory analyses have been carried out in order to compare the seismic performance of a conventional c oupled wall building to alternative designs incorporating VCDs. Results highlight the improved performance of VCDs over RC coupling beams at all levels of seismic hazard. A design pro cedure for seismic-critical buildings is proposed.
