Shear panel dampers consisting of stiffeners and panels surrounded by four flanges are used as aseismic hysteretic dampers for buildings in Japan. Cracks can form easily [...]

Viscous damper is one of the most widely used velocity-dependent dampers in Japan. It can reduce building responses of wide range of magnitude, such as micro-vibration ca [...]

The Great Tohoku-oki earthquake of March 11, 2011 (the ‘311’ earthquake) showed that the intensity of ground shaking for some site location has been as large or large [...]

In this paper, application of passive control devices to small wooden structures is introduced. Chapter 2 discusses the seismic behavior and the performance of structural [...]

A hysteresis model for seismic response analysis called “deformation history integral type model (DHI model) has been proposed for reproducing hysteresis of high dampin [...]

Viscoelastic dampers dissipate energy through shear deformation of the viscoelastic materials; generating heat within the material causing it to soften. Therefore, under [...]

Hanging type cable rack system partially had serious damage during the Tohoku-oki Earthquake, March 11, 2011. The objective of this paper is to understand the seismic per [...]

This paper proposes accurate modeling of a new high-stiffness viscoelastic material for vibration control of a structure. The temperature sensitivity of the material is p [...]

The performance of passively controlled buildings depends not only on dampers but also on frame members and connections. The frame members are subjected to bending moment [...]

Shaking table test of full-scale 4-story moment frame was carried out at E-defense, one of the largest shaking tables in the world. The objectives of this experiment are [...]
