Abstract In this paper, a hybrid mass damper (HMD) and its hyperstability thanks to power flow approach are studied. The HMD proposed combines an active control system with optimal passive device. initial is electromagnetic Tuned Mass Damper (TMD) the law modified velocity feedback phase compensator. resulting controller theoretically hyperstable ensures fail-safe behavior. Experiments performe...

In this paper, the two-dimensional vibration controls of a power transmission tower with a pounding tuned mass damper (PTMD) under multi-component seismic excitations are analyzed. A three-dimensional finite element model of a practical power transmission tower is established in ABAQUS (Dassasult Simulia Company, Providence, RI, USA). The TMD (tuned mass damper) and PTMD are simulated by the fi...

In the present paper, active control system is used in different heights of the building and the most effective part was studied where the active control system is applied. The mathematical model of the building is established in MATLAB and in order to active control the system FLC method was used. Three different locations of the building are chosen to apply active control system, namely at th...

In this paper the role of solid nonlinearity on fluid–structure interaction (FSI) is studied. First a simple mass-spring-damper system with third-degree spring coupled linear sloshing to study effect nonlinearity. It shows that even both systems show similar behavior in free vibration tests, but caused 50% less amplitude vibration. Then higher order tuned liquid damper which modeled by boundary...

The tuned liquid multiple column damper (TLMCD) is a variation of the (TLCD) that includes vertical columns. A new damping system embeds TLMCDs within reinforced concrete shear wall systems, termed (TLWD), proposed, augmenting traditional structural component with energy dissipation capabilities. objective this study to assess mitigation and strength trade-offs in designing TLWDs demonstrating ...
