Tuned mass damper (TMD) is a popular vibration absorber. To improve the seismic
protection performance of a bi-directional passive TMD, a bi-directional semi-active TMD …

Magnetorheological (MR) materials are a group of smart materials used in new technologies
with controlled reliability. The development of these materials is expanding, starting from MR …

Yielding can be emulated in a structural system by adding an adaptive negative stiffness
device (NSD) and shifting the yielding away from the main structural system, leading to the …

In recent years different inerter-based vibration absorbers (IVAs) emerged for the
earthquake protection of building structures coupling viscous and tuned-mass dampers with …

The estimation of critical seismic response of a structure is complicated in nature due to the
uncertain distribution of the internal forces under multidirectional seismic excitations. One of …

This paper presents the performance of a new magnetorheological elastomer-based semi-
active/passive variable stiffness and damping isolator (VSDI) in a scaled building system …

This paper presents the benchmark problem definition for seismically excited base‐isolated
buildings. The objective of this benchmark study is to provide a well‐defined base‐isolated …

Pseudo‐negative‐stiffness dampers or PNS dampers are controlled variable dampers that
produce negative‐stiffness hysteretic loops. Negative‐stiffness hysteretic loops are …

Fractional order PID (FOPID) controllers are introduced as a general form of classical PID
controllers using fractional calculus. As this controller provides good disturbance rejection …

Sample controllers for a three‐dimensional smart base‐isolated building benchmark
problem with linear and frictional isolation system are presented in this paper. A Kalman …
