Abstract

Energy absorbing technique: challenge of proportioning V. Shustov INTRODUCTION Added energy dissipation technique is a sort of remedy for earthquake vulnerable structures and as any remedy it should not be prescribed indiscriminately. Therefore, the optimum proportioning the ingredient parameters is a priority for successful implementation of the technique. It should answer the following questions: When? Where? What? How many? MYTH'S DISSOLUTION The vivid pictures of the dynamic magnification factor plots from the textbooks, as well as the flocks of ubiquitous re- sponse spectra are feeding a universal belief in valuable contribution of the added heavy damping to the earthquake performance of building structures. The only problem that seems to be solved is choosing the proper devices able to dissipate a possibly larger amount of seismic energy. But the energy dissipation is a result of mechanical work per- formed by the force of resistance associated
