Building structures around the world have been designed using various framing methods. In Japan, the two-way momentresisting frame structures, which is designed as a 3D s [...]

In the 2011 off the Pacific coast of Tohoku Earthquake, a lot of suspended ceilings suffered damage and collapsed due to lack of their seismic performance. New seismic st [...]

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 [...]

Typically steel moment-resisting frame structures in the United States, similar to many super-high-rise framed-tube structures being constructed in Japan, have stiff beam [...]

Elasto-plastic dampers can reduce story drift of the frames and retain elasticity of structural members by adding hysteretic damping and stiffness. Extremely severe earth [...]
