ABSTRACT
Application of the concept of removable dissipative members to eccentrically braced frames (EBFs), where links act as dissipative zones, is presented in Figure 1 (Stratan & Dubina 2004, Dubina et al., 2008). The connection of the link to the beam is realized by a flush end-plate
1 INTRODUCTION
Different strategies can be employed in order to reduce damage to structures under moderate to strong earthquakes. The most radical solutions are base isolation and various implementations of active and semi-active structural control. Other strategies rely on supplemental damping conferred to the structure through various devices based on viscous, friction, or yielding dampers. More or less efficient for reduction of structural damage, all these solution have the disadvantage of requiring specialised knowledge at the design stage and during erection, need for careful maintenance and high initial cost.
