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 [...]

An anchor-bolt-yield-type column base shows slip-type restoring force characteristics. A column base subjected to constant axial and cyclic horizontal forces shows more c [...]

One of authors has proposed a scheme for Internet-based collaborative structural analysis (CSA) in which many researchers worldwide can collaborate and unify their differ [...]

A wedge device consisting of a wedge, a counter-wedge and a spring, is proposed by the authors. The device is applied to earthquake-resistant elements to provide more eff [...]

A full-scale experiment to simulate collapse of a 4-story steel building was conducted using E-Defense shake table facility. The specimen consists of beams of wide-flange [...]

The building structural engineers can’t necessarily predict the fabrication cost from the structural weight appropriately. It is because the fabrication cost for steel [...]

A main reason for early tensile brittle fracture of the anchor-bolts in the steel exposed-type column bases under the past earthquake is that the thread part has the decr [...]
