Assessing the dynamic response of a steel pipeline to a strong vertical mining tremor using the multiple support response spectrum method
This paper presents an analysis of the dynamic response of an overground steel pipeline during a strong mining shock. The analysis was conducted using various calculation methods- a time history (THA), a response spectrum (RSA) and a multiple support response spectrum analysis (MSRS). For the THA and MSRS methods, non-uniform effects of ground excitation were taken into account. During the analyses, the bending moment was calculated. On the basis of obtained results, it can be noted that the non-uniform effects had a significant impact on the dynamic behaviour of the pipeline and it was indicated that the MSRS method led to more accurate estimation than the RSA.
Streszczenie
W artykule przedstawiona została analiza odpowiedzi dynamicznej gazociągu na rzeczywisty wstrząs górniczy. W obliczeniach zastosowano metodę całkowania równań ruchu (THA), spektrum odpowiedzi (RSA) oraz wielopodporowego spektrum odpowiedzi (MSRS). W metodzie THA i MSRS uwzględnione zostały efekty związane z nierównomiernością wymuszenia kinematycznego. W trakcie analizy obliczono momenty zginające w konstrukcji, na których podstawie zauważono, że nierównomierne wymuszenie ma wyraźny wpływ na wartość odpowiedzi dynamicznej.
