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: damper-cable system (DCS). 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. This device allows the cable to slip inside and move with respect to the structure. In this report the experimental results obtained during the test carried out at Enel.Hydro on the single DCS in the straight and deviated configuration ara analysed and compared with the results obtained with numerical analyses performed with ABAQUS code. The results are compared with the ones obtained with the model proposed by the system manufacturers and with a modified model, developed analysing the tests results, that batter reproduces the DCS behaviour.
