Canadian Seismic Design Considerations for Outriggers Used in High-Rise Buildings
A damped outrigger system is an effective structural scheme that has been realized in Canadian construction in the past decade for resisting seismic and wind loads. These outriggers increase the stiffness of reinforced concrete core walls, reduce the moment demand within the walls, and add additional energy dissipation. Essentially, the outrigger system acts as a rotational spring providing additional moment resistance and rotational stiffness, which leads to lower drifts and displacements. Although the outrigger systems demonstrate desirable seismic performance, no seismic design procedures exist within Canadian building codes. In this study, a comprehensive parametric analysis is done, providing empirical relations for the dynamic response of outrigger buildings. Prototype outrigger-wall buildings are designed with the proposed design methods, and the challenges of designing these systems are discussed in detail. This study is a step towards new seismic design guidelines for outrigger buildings in Canada.
