This study involved a series of pipeline experiments, encompassing tension tests, bi-axial tension tests, and 4-point bending tests, to investigate the failure mechanisms of an 8-inch TR-XTREME ductile iron pipe manufactured by US Pipe. These experiments were equipped with distributed fiber optic sensors, continuously capturing strain profiles along the pipeline. Additionally, the study involved the meticulous construction and rigorous validation of finite element models using the wealth of experimental data at its disposal. This seamless integration of empirical insights and numerical modeling facilitated a comprehensive inquiry into the failure mechanisms associated with the 8-inch TR-XTREME ductile iron pipe from US Pipe. The results of this investigation not only enhance our comprehension of innovative joint systems but also offer indispensable insights for propelling the design and implementation of earthquake-resistant water pipelines to new heights.
