چکیده مقاله :
Welding is a repair technique to remove discontinuities and damaged areas in buried pipes. this is an important issue in mechanical and civil engineering structure and many studies focused on this topic and related issues. Repaired areas should be covered by composite layers for stiffening. The current study focuses on a specific buried drain pipe that is repaired by longitudinal weld and stiffened by glass/epoxy composite. To this end, pipes covered by various numbers of composite layers were modeled in Abaqus and loaded by external lateral pressure to determine buckling behavior. Modeled pipes had a longitudinal dent that represents the weld effect. Results showed the buckling resistance exponentially increases with the number of composite layers. Finally, the reliability and accuracy of numerical simulations were investigated using the experimental approach. In this step, three pipes were tested. the differences between numerical simulation and experiment were around 20 percent. This difference is due to composite manufacturing and stiffening procedures and is acceptable.
