Various dynamic pipe support systems, ranging from very flexible to very stiff support configurations have been investigated. In general it was observed that the peak dynamic support loads, at least at some locations, were significantly higher than those predicted by the design calculations.enaccelerationBeschleunigungBetriebslastenanalyseBetriebslastensimulationearthquake simulationErdbebensimulationfrequency spectrumFrequenzspektrumGanzzellenversuchKraftwerkKraftwerksbauoperational load analysisoperational load simulationpipe linepower plant constructionreactor constructionreactor safetyReaktorbauReaktorsicherheitRechenverfahrenRohrleitungSpannungsanalysestress analysistheoretical method620conference paper
