Abstract This thesis investigates the mitigation of excessive vibrations in multistory steel buildings using linear and nonlinear TMDs. Three types of stiffness mechanisms of TMDs were studied: linear, essential nonlinear (without linear part), and nonlinear (with linear part). Also, an algorithm of the nonlinear direct integration dynamic analysis for a set of eight earthquakes possessing a diverse frequency content was developed by MATLAB software. The minimum dynamic response of the structures for each seismic event was obtained by opting for the proper parameters of the damper via an optimization process |
