For normal-scale buildings, the structural design against large earthquakes of foundation structures such as a pile head joint are not required legally because of unclear [...]

In the seismic design, beam-to-column connections should prevent early fracture in order to keep enough energy absorption capacity of members after beam yielding. Especia [...]

From lessons learned in the 2011 Tohoku earthquake, it becomes clear that the quick procurement of an emergent public shelter is very important in time of disaster. Struc [...]

In the 1995 Kobe earthquake, many steel structures suffered damage at beam-to-column connections. And in those damaged buildings, fractures of a beam flange at the beam-t [...]

Braced frame structures are used for school gymnasiums and factories with large space. It is very important building which will be used as emergency public shelters in ti [...]

This paper presents a new method of reinforcement of two-story mass-varying structure using inertial mass. In a massvarying structure like an elevated station, the mass o [...]

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 [...]

The framed-tube structure consists of rigid moment frames in the perimeters and floor-system which provides lateral-supports to prevent perimeter column buckling. When pe [...]

A shaking table test on a full-scale steel building was conducted at the E-Defense three-dimensional shake table facility to evaluate structural and functional performanc [...]

The collapse process of building under severe earthquake is not clarified yet. In order to make it clear, shaking table test of a full-scale building at E-Defense is cond [...]
