Dynamic analysis of three story steel frame with impact mass damper

Abstract

PEER is organizing a blind prediction contest for predicting the experimental results obtained from a Shaking Table test campaign carried out at the PEER Center, Berkeley, California, in collaboration with the University of Trento, Italy. The experimental tests, performed on a steel Moment Resisting Frame, pursued the aim of physically demonstrating the effectiveness of a novel device for seismic action mitigation, called Impact Mass Damper (IMD). The basic operating principle of the device is to induce counteracting impulsive forces on the structure. This research presents an entry based on the dynamic analysis by using the computer program SAP2000 to identify the seismic responses: displacement, acceleration, base shear and impact force under different ground motions. The comparision between two models shows the effect impact mass damper on structure behavior.
