The paper investigates the seismic performance of a novel passive vibration isolation and damping device termed Extended KDamper (EKD). concept is applied to representative two-span highway bridge, initially designed on conventional (CSI) bearings. An optimization process developed executed design EKDs, underscoring importance accounting for motion variability. Compared CSI, incorporation EKDs ...

In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...
