Abstract
In the frame of the SPIDER (Strands Pre-stressing far Internal Damping of Earthquake Response) Project a new system far the protection of buildings against the earthquake is studied. The project studies the application of pre-stressed cables in series with tension spring dampers. The cable is fixed at one of the ends to the basement of the building and, at the other end, to the upper part of the building. The shock absorber, coupled in series with the cable, is located close to the basement far easy installation and maintenance. The cable is connected with a special device at each of the floor. In this report the application of this Damper Cable System (DCS) of a generic four storey buildings is studied. The building equipped or not with DCS is submitted to several time-histories, real and artificial, and the dynamic behaviour is analysed in order to evaluate the effects of the system on the protection against an earthquake. The analyses ara repeated on the same structure equipped with the cables but without any damper. This solution provides an increased building stiffness without any damping and the comparison with the same building equipped with a complete DCS allows evaluating the damper effect. The numerical analyses were performed by means of the Abaqus Code.
