In the experiment, steel pipe elbows and lead pipe elbows were used as the specimens. Obtained failure modes are classified into following three modes; 1) fatigue failure, 2) ratchet-collapse, and 3) large deformation. From the experiments and a lot of preceding studies, the most possible failure mode would be the fatigue failure. Under some extreme conditions, such as large primary stress was caused by the deadweight, ratchet-collapse or large deformation would occur. It seems that the direction of the gravity affects a lot on the occurrence of the ratchet-collapse. The primary stress level would also be an important factor. But other factors to dominate failure behavior are still not clear, so further experimental or analytical studies are necessary.","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"In order to investigate the failure modes of piping systems under excessive seismic loads, a series of shaking table tests on elbow pipe specimens has been conducted.
