Passive Control via Mass Dampers: A Review of State-Of-The-Art Developments

Passive control systems are practical systems that use the system's energy to absorb its energy to control the dynamic effects on the structure. In the control of these systems, which store energy with the help of a spring and mass, the effect of mass and spring is great. Based on this logic, different types of passive control systems are derived according to the type of material used. Tuned mass dampers (TMD) and tuned liquid dampers (TLD) in the passive control group are often used to solve various engineering problems. In these two systems, which have the same properties, a solid mass is usually chosen for TMD, while this mass is liquid for TLDs. In this study, passive control systems, which have important effects on building control, are explained in general terms, the historical development of TMDs and TLDs from the early times when the concept of structural control emerged until today, and the studies that have been done are included.
