弾塑性応答を考慮した配管系の耐震安全性評価

（その1 弾塑性解析による応答挙動評価のばらつきと影響因子の考察）

Inelastic benchmark analyses and parametric analyses on a pipe element test and a piping system test are conducted to investigate the variation of the elastic-plastic analyses results. Based on these analytical results, it is assumed that setting the yield stress has a great influence on the inelastic analytical results. From the results of the parametric analyses, it is confirmed that the variation in the analytical results among the analysts would be reduced by unifying analysis procedure.
