Abstract

This paper, aims to investigate function of a pendulum tuned mass damper and optimizing of its dynamic parameters in decreasing roof displacement and base forces (shear and moment) of a tall building under a scaled horizontal component of earthquake (the Manjil earthquake on the Qazvin station). Diagrams of relative maximum displacement of roof (maximum roof displacement in building without pendulum to correspond value in building with pendulum), relative maximum base forces (maximum base shear and moment in building without pendulum to correspond values in building with pendulum), and dynamic parameters of pendulum (stiffness and damping coefficient), all in optimum situation, have been plotted. Finally, Maximum displacement of pendulum’s mass has been plotted for checking the strike problem and determining the minimum required length of pendulum’s span.
