Tuned Mass Damper Design for Slender Masonry Structures: A Framework for Linear and Nonlinear Analysis

The paper presents a proposed framework to optimize the tuned mass damper (TMD) design, useful for seismic improvement of slender masonry structures. A historical chimney located in northern Italy was considered illustrate TMD design procedure and evaluate performance system. optimization process subdivided into two fundamental phases. In first phase, main parameters were defined starting from dynamic behavior by finite element modeling (FEM). series linear time-history analyses carried out point structural improvements terms top displacement, base shear, bending moment. second masonry’s nonlinear considered, fiber model implemented. Pushover performed obtain capacity curve structure TMD. results analysis reveal effectiveness
