| Research Abstract |
Structural members in steel-framed buildings are susceptible to fracture during the attack of severe earthquake, as reported about the building damages in Kobe at the 1995 Hyogoken-Nambu Earthquake. The fracture possibly causes the fatal loss of safety of buildings. Earthquake motions make steel structural members experience cyclic deformations with random amplitudes, during which the fracture is triggered. In this study, pre-fracture loading cycles and deformation capacity under such random amplitudes were experimentally investigated and the evaluation methods were proposed. Applying these methods, the seismic design will be able to develop steel-framed buildings free from fracture at the future-coming events of big earthquakes.
