This paper introduces a novel methodology for the optimum design of linear tuned mass dampers (TMDs) to improve seismic safety structures through Whale Optimization Algorithm (WOA). The algorithm is aimed reduce maximum horizontal peak displacement structure, and root mean square (RMS) response displacements as well. Furthermore, four additional objective functions, derived from multiple weight...

This article deals with the applicability of passive tuned mass damper (PTMD) for reducing the dynamic responses of structures under near-fault earthquake excitations. Three types of pulse-like time functions are employed to simulate the near-fault ground motion. The vibration control effectiveness of PTMDs is extensively investigated through the comparisons of response spectrum and response ti...

This article presents a theoretical study aimed at improving effectiveness of the isolation system of a building by adding magneto-rheological (MR) dampers that act in parallel to the rubber bearings (RB). To this end, the building itself is modeled with uni-axial elements that consider axial, shear and flexural deformations. Nonlinear elements that include RBs and MR dampers, whose response is...
