Ferrofluids are a type of nanometer-scale functional material with fluidity and
superparamagnetism. They are composed of ferromagnetic particles, surfactants, and base …

Stay cables are one of the key elements of cable-stayed bridges and are characterized by
lightweight, low inherent damping, and high flexibility. They are continuously subjected to …

Conventional base isolation has been commonly used to protect structures against
destructive earthquakes. However, base-isolated structures can be vulnerable to ground …

This study proposes a strategy of utilizing novel lead viscoelastic damper (LVD) to improve
the seismic performance of the weakened reinforced concrete (RC) frame under mainshock …

A novel shape-optimized composite metallic yielding damper (SCMYD) is proposed to
improve the energy dissipation capacity under multiple levels of earthquakes. The SCMYD …

Most isolators have numerous displacements due to their low stiffness and damping
properties. Accordingly, the supplementary damping systems have vital roles in damping …

Structural vibration is a widespread issue occurred in the field of civil engineering. The
passive energy dissipation devices are being increasingly popular for protecting structures …

Pendulum-tuned mass dampers (PTMDs) are attractive to control horizontal vibrations in
buildings. In addition to their performance, they present relatively low cost, and they are easy …

A novel metallic damper with torsional-yielding on the circular steel tube, called torsional
steel-tube damper (TSTD), is proposed in this paper. Four specimens are designed for …

This paper proposes a novel energy dissipation shear key (ED shear key) for small-to-
medium-span highway bridges using butterfly-shaped steel plates for enhanced energy …
