000010655 520__ $$2eng$$aAn enhanced toggle-brace-damper (TBD) installation configuration with the damper directly connected to the beam-column joint is introduced. Magnification factor for damper displacement and force are investigated. Expression for prediction of equivalent linear viscous damping ratio provided by the improved TBD systems installed in a building is then introduced. For practical application, a simplified procedure for design and analysis of building incorporating TBD systems is proposed based on Chinese design response spectrum, in which the damping coefficients of the dampers that are proportional to the relative modal displacements in the corresponding stories are distributed over the height of a structure to satisfy the given performance objective. The validity of this method is verified by nonlinear response history analysis (RHA). The study shows that this improved damper installation configuration not only decreases significantly floor displacement response but reduces story shear demands when compared with the conventional installation configurations of TBD and diagonal brace-damper.
