The ductility factors of nonlinear SDOF systems at Service Limits Ds “using elastic analysis design” in JEAC4601 are investigated, and it was confirmed that the ductility factors depend on the natural frequencies of systems, seismic motions and c

A design seismic motion for design of nuclear power plant have been increased in Japan since Tohoku earthquake in 2011. Consequently, piping systems under the design seismic motion are possibly deformed plastically. Elastic-plastic FEA (Finite Elemen

For the seismic fragility assessment of piping systems in a nuclear power plant, the failure probability of piping systems is calculated elastically under the assumption that ductile rupture occurs. However, some previous studies have reported that t

Loads applied to structures by means of vibration can be classified into load-controlled and displacement-controlled loads. The realistic elastic-plastic behavior of structures subjected to seismic loads is not fully understood, and the classificatio

When designing and evaluating the strength of the piping system of a nuclear power plant, ductile rupture or plastic collapse is often assumed to be the limit state. However, previous studies have reported that the primary failure mode of piping syst

An inelastic response-spectrum-analysis method for multi-degree-of-freedom systems was proposed. The method has lower analysis loads and good outlook given by the inelastic response spectrum like the elastic response-spectrum-analysis method, and is
