Analysis of the earthquake effect on a pipeline broken by a circumferential crack
Jiří Novotný, Jiří Novotný Jun.
pages 197 - +10p., full text

Dynamic effects of seismic excitation and of the steam line break in the weld of the steam pipe and the steam collector during an earthquake are analyzed. Generated synthetic acceleration-time histories based on given floor response spectra are used to excite the system. To model the process of a circumferential crack evolution leading to the pressurized pipe rupture and of the whip restraint function a special element in the programme SYSTUS is used. Whip of of the steam line is analyzed and its effect on the steam generator considered.
