碩士 === 國立中央大學 === 土木工程研究所 === 98 === The purpose of using damper in a structure is to reduce the seismic response of the structure by using the energy dissipation mechanism of the damper. Among many dampers developed over the past years, a type called Added Damping and Stiffness (ADAS) device uses the steel plate as the damper. It has the X type and triangular type and was shown to have good performance in dissipating energy. It has been pointed out that the axial forced developed in the X-shape ADAS can affect its efficiency, whereas for the improved triangular type the welding qualities can affect its efficiency. This research focused on developing a new steel damper in the form of RC building structure. In this study the Three-pin steel damper has good performance in dissipating energy. It’s energy dissipation mechanism is stable with a large area of hysteresis loops, while it can eliminate the defects of the X type and the triangular type device. A 14-story RC building structure is use to demonstrate the purpose of design procedure. The three-pin steel damper will be install in this RC building structure. The effectiveness of the three-pin steel damper are verified by using static pushover analyses and nonlinear dynamic analyses.
