By adapting this amplification, a static analysis is sufficient to account for both static and dynamic behaviour in design. Consequently, all structures independent of stiffness and mass properties are provided with the same degree of dynamic amplification which can produce a high level of conservatism in their design.  \nThe objective of this thesis is to gain a better understanding of the dynamic behaviour of pipe rack steel structures subjected to explosion loading. By achieving this, the aim is to provide structural engineers with knowledge leading to a more accurate design in future projects.  \nTo accomplish this, finite element analyses of three pipe racks have been performed and their respective DAFs have been calculated. The results show that DAFs vary between the structures, which indicate that the dynamic behaviour depends on one or several parameters. In addition, the results indicate that the magnitude of the DAF is dependent on what the selected inputs to calculate the DAF are. However, as no obvious affinity between the parameters of the structures and the dynamic amplification is observed, a parametric study was required to increase the understanding of how different parameters affect the DAF. The results from the parametric study show the same variation of the DAF as in the analyses of the first three pipe racks. The resultseven reveal DAFs higher than the DAFs currently used in design procedures. Moreover, the results show that the mass distribution has a significant influence on the dynamic behaviour. In addition, the results indicate that the DAF currently utilized in design is non-conservative. However, the rather large scatter of the results implies that further studies are desired.  \nKey words: pipe rack, dynamic behaviour, explosion, DAF, FEA,  \npipe mass distribution, base shear, overturning moment  \nDynamisk respons av fackverksstrukturer i stål på grund av explosionslaster Examensarbete inom masterprogrammet Konstruktions-och byggteknik ANTON STADE AARØNÆS, HANNA NILSSON  \nInstitu","cbCailIyDdc6JNa6","https://ap.wps.com/l/cbCailIyDdc6JNa6","pdf",2993893,74,"English","# Abstract\n## Objective and approach\n## Finite element analyses and DAF calculation\n## Parametric study and key findings\n## Conclusions\n## Keywords","[{\"question\":\"Why is a simplified dynamic amplification approach used in explosion analysis of steel pipe racks?\",\"answer\":\"A fixed dynamic amplification factor is used to scale static loads so that static analysis can account for both static and dynamic behavior in design.\"},{\"question\":\"How did the thesis determine the dynamic amplification factor (DAF) for pipe racks?\",\"answer\":\"It performed finite element analyses of three pipe racks and calculated each rack’s respective DAF values.\"},{\"question\":\"What key conclusion does the thesis draw about DAF and design conservatism?\",\"answer\":\"DAFs vary between structures and depend on selected inputs; the currently used design DAF is indicated as non-conservative, and further studies are recommended due to result scatter.\"}]","Dynamic response of pipe rack steel structures to explosion loads - Master’s Thesis | PDF",1792856802,186]
