Abstract:

To reduce the dynamic response of a building with a given height and plan area to wind load, aside from inherent damping of the building, the designer has a few options available to him/her. Increasing the stiffness by adding mass and/or increasing damping by utilization of dampers. Added damping is more economical than adding stiffness or mass to control dynamic response. The function of a damper in the building is to transfer a portion of the vibratory energy of the structure into heat and dissipate this heat into the surroundings. This paper will discuss the design and the employment of certain types of dampers for the Columbia Center Building in Seattle, Washington.
