Analytical, Numerical and Experimental Studies for SERB TEL-150 New Romanian Seismic Dampers Used in Foundation Buildings Damping System

This paper presents analytical, numerical and experimental studies of SERB TEL-150 new Romanian devices for dissipation of seismic energy for buildings affected by Romanian Vrancea earthquakes. These devices were invented to be positioned at the foundation of buildings and were tested in static cases. The purpose of these studies is to determine the analytical model of the special shape hysteresis of these new devices which is necessary to obtain the mathematical equation for these hysteresis curves. The experimental and the numerical analysis of SERB TEL-150 were performed in order to determine the experimental and the numerical hysteresis curves which are to be modeled with a modified Bouc-Wen model. These devices were invented by PhD.eng. Viorel Serban (CITON – Center for Technology and Engineering for Nuclear Projects) and they were used for equipping NAVROM building in Galati, Romania.
