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 the numerical analyses performed by means of the Abaqus Code this device is modelled using 'contact elements'. These elements are included in the element library of the code but are not commonly present in other codes, besides the use of these elements can cause convergence problems and increment in the calculation time. In this report is presented a simplified toll that allows avoiding the use of contacts elements in modelling the connecting device maintaining the same features.
