内容記述 |
The safety factor for joints was investigated, which is at the welded joint of the steel structure in consideration of Column-Overdesign-Factor (COF). Considering the rupture of the welded joint in the steel structure, it is difficult to obtain the structural reliability containing brittle failure by general reliability analysis. In order to perform the reliability analysis including the welded joint rupture, these failure modes of the structure were classified to the mutually exclusive events by COF and the welded joint performance. The welded joint strength was predicted by Bayes’ theorem, using the beam strength as a prior distribution and the experiment's results of welded joint strength. As a result, the ratio of failure probability with the welded joint rupture became about 3% of the total failure probability. When it compared to the layer collapse probability, the COF is higher, the ratio of failure probability including the weld joint rupture is increased. |
