Stiffening effects-controlling sizing procedure of ADAS dampers in seismic retrofit of frame structures

Added Damping and Stiffness (ADAS) steel dissipators are among the most classical devices installed in dissipative bracing systems for advanced seismic retrofit of frame buildings. An energy-based sizing procedure is formulated this study class dampers, where total number constituting plates directly related, without iterative steps, to supplementary damping energy required jointly reduce stress states structural members storey drifts. The stiffening effects braces expressly controlled, so as compensate increase shears induced by their incorporation skeleton. demonstratively applied design a 6-storey reinforced concrete building, explicate discuss use its analytical relations relevant limitations practice. evaluation performance structure retrofitted conditions allows comparing response system with hypotheses at stage.
