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

For seismic design of components, elastic response spectrum analysis, which is based on linear response using elastic response spectrum, is generally used as a dynamic analysis of multi-degree-of-freedom(MDOF) systems not only elastic response but al

A constant ductility response spectrum (CDRS) readily provides the yield strength of a single-degree-of-freedom (SDF) system necessary to limit the ductility imposed by a ground motion to a specified value. The allowance of inelastic deformation of a

The relationship between the natural period, strength, and the response of piping systems subjected to seismic motion was investigated for straight piping systems and piping systems with elbows. The strength of each mode of a piping system subjected

In order to evaluate seismic responses considering the elasto-plastic properties of equipment and piping systems, nonlinear time history analyses are utilized. When the analyses are used for seismic evaluation of equipment and piping systems in nucle

In previous reports, it was shown that the cumulative absolute velocity (CAV) for each wave of the pipe seismic response corresponds to the vibration stress amplitude. A new seismic fatigue evaluation method was proposed by applying this relationship

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

In a previous report, a new method of calculating the approximate seismic cumulative fatigue damage of plant pipelines was developed, in which the sum of the cumulative absolute velocities (CAV) of the pipeline response per cycle was calculated, and
