The Japanese seismic design code adopts a factor Ds for chevron-braced frames to consider the seismic force reduction due to the ductility. The Ds value varies from 0.25 [...]

The objective of this research is to identify the maximum drift angle sustained by a story level during an earthquake event. To accomplish this, strain patterns in suitab [...]

In the standard base plate connection in steel structures, namely the exposed column base, the shear force is resisted by the combination of anchor bolt shear and frictio [...]

A shallow embedded steel column base consisting of an exposed column base and a covering reinforced concrete (RC) floor slab is examined. A series of tests are conducted [...]

A series of full-scale shaking table tests was conducted for a full-scale 21-story steel building frame subjected to a series of long-period, long-duration ground motions [...]
