...C. G. Karvelas; G. Chatzopoulou; A. D. Zervaki; S. A. Karamanos; E. Strepelias; X. Palios; S. N. Bousias The paper presents a combined experimental and numerical investigation of cyclic loading response of an internally pressurized 8-inch-diameter steel piping system. The piping system comprises...

...Izumi Nakamura; Naoto Kasahara To investigate the failure behavior of piping systems under severe seismic loads considering beyond design basis event (BDBE), an experimental approach to use pipes made of simulation materials was applied. “Simulation material” means the substitute material for steel...

...Akira Maekawa; Tsuneo Takahashi This study presents the response mitigation effect of piping systems by inelastic seismic design based on elastic–plastic property of steel pipe supports. The inelastic seismic design to control vibration by absorbing energy using elastic–plastic properties...

...Akira Maekawa; Tsuneo Takahashi This study describes inelastic seismic design of piping systems considering the damping effect caused by elastic–plastic property of a pipe support which is called an elastic–plastic support. Though the elastic–plastic support is proposed as inelastic seismic design...

...Tao Zhang; Frederick W. Brust; Gery Wilkowski; Do-Jun Shim; Jinsuo Nie; Charles H. Hofmayer; Syed A. Ali Nuclear power plant safety under seismic conditions is an important consideration. The piping systems may have some defects caused by fatigue, stress corrosion cracking, etc., in aged plants...

...Izumi Nakamura; Akihito Otani; Masaki Shiratori Pressurized piping systems used for an extended period may develop degradations such as wall thinning or cracks due to aging. It is important to estimate the effects of degradation on the dynamic behavior and to ascertain the failure modes...
