Dynamic Response of Buried Pipelines Retrofitted with Concrete Canvas Panels Under Blast Loading
In this study, the effect of concrete canvas (CC) panels on retrofitting of buried pipes against surface blast loads in different situations is investigated. The variable parameters studied are CC panels thickness (20 and 30 mm), the number of CC panels (1, 2, 3), soil type (two different soils), and the layout of CC panels (complete wrapping and U-wrap), respectively. For this purpose, the finite element method (FEM) is used to simulate models. In the finite element model, an explosive charge of 45 kg was simulated at a distance of 1 m above the steel pipeline. Validation of FEM used in simulating the present study was examined through comparing with the experimental results, and a good agreement was observed. The most important results show that the maximum stress and displacement in buried pipelines retrofitted with CC panels that are subjected to surface explosive loading are a function of thickness, number, and layout of CC panels, and to achieve optimal performance of CC panels, a combination of these parameters should be evaluated.
