Design of Structure and Damping System to Control Motions of the Park Tower, Chicagoby Chris Stefanos,
Brian Breukelman, P.E.,
Abstract: Park Tower, a 67 story condominium/hotel project currently under construction on the Magnificent Mile, Chicago, IL, will be the first building in North America in recent times that utilizes a passive Tuned Mass Damper (TMD) to reduce wind-induced accelerations. The structural system is a cast-in-place concrete frame founded on caissons bearing on hard pan & dense silt approximately 95' below grade. A perimeter tube frame of spandrels and columns is used in conjunction with shear walls to provide the lateral stiffness required to resist the design wind loads.
