dc.description.abstract Les essais expérimentaux récents ont montré que les équipements de type lignes de tuyauteries souffrent des damages aux action 15-20 fois plus grandes que les actions qui conduisent à la ruine des structures de résistance. Pour garantir d’un dommage inexistant en réalité (instabilité plastique) les concepteurs sont amenés à limiter les déplacements des lignes de tuyauteries en les rigidifiant. Une solution pour résoudre ce problème est de multiplier les supports classiques et les dispositifs amortisseurs autobloquant. Ce travail présente la méthode de linéarisation équivalente pour les systèmes non linéaires soumis au choc. en_US
dc.description.abstract Încercările dinamice recente au arătat că echipamentele tip conductă se degradează la acţiuni de 15-20 ori mai mari decât acţiunile care conduc la colapsul structurilor de rezistenţă. Faptul că aceste structuri se comportă mai bine decât prevăd codurile şi standardele poate să apară ca liniştitor dar nu şi economic. Pentru a garanta o degradare inexistentă în realitate (instabilitatea plastică) proiectanţii sunt obligaţi să limiteze deplasările conductelor şi să le rigidizeze. O soluţie pentru rezolvarea acestei probleme este de a majora numărul suporturilor clasice precum şi a dispozitivelor de amortizare auto-blocante. Lucrarea prezintă o metoda de liniarizare echivalenta a sistemelor neliniare supuse la soc. ro
dc.description.abstract The recent dynamic tests shows that the “pipe” equipment are degraded under the loads from 15 to 20 times greater than those actions that leads to the collapse of the resistance structures. Because these structures behave better than the requirements of the standards and codes, is a reassuring fact but not also economic. In order to guarantee a non-existent degradation (the plastic instability) the designers are forced to limit the pipe’s displacements and to reinforce them. A solution in order to solve this problem is to increase the number of classic supports and also the number of self-blocking damper devices. The presence of the functional legerities complicates the dimensioning introducing a shock non-linearity, in case of sudden movements, between the structure and these supports. en
dc.description.abstract Недавние динамические исследования показали, что принад-лежности типа трубопровода деградируют при нагрузках в 15-20 раз больше чем нагрузки, которые приводят к разрушению самих конструкций. То что эти конструкции лучше чем предусматривают различные коды и стандарты может показаться успокоительно, но не экономически. Для обеспечения несуществующей в реальности деградации (пластическая нестабильность) проектанты обязаны ограничить перемещения трубопроводов и ужесточить их. ru
