DYNAMIC TESTING OF FULL-SCALE IRANIAN VISCOUS DAMPERS

Located at the Science and Technology Park of University of Tehran, Behsazan Larzeh Davam Co. has developed a patented technology to systematically design and manufacture linear and nonlinear fluid viscous dampers in Iran. Designing and manufacturing of a fluid viscous damper is a multidisciplinary task which calls for significant expertise in different branches of science including, structural dynamics, fluid and solid mechanics, Computational Fluid Dynamics (CFD), etc. In this study, experimental results of three full-scale viscous dampers are presented and performances of the manufactured viscous dampers are discussed. All prototype specimens have been designed and manufactured by Behsazan Larzeh Davam Co. The main characteristics of the considered viscous dampers are shown in Figure 1.The viscous dampers have been tested in the International Institute of Earthquake Engineering and Seismology (IIEES) of Iran using a 500 kN dynamic actuator and a unique rocking set-up, as shown in Figure 2. The set-up is designed to directly transfer displacements of the actuator to the damper while preventing its out-of-plane motions.
