Pipeline joints (ductile‐iron pipes with push‐on rubber gaskets) of various diameters (100 mm [4 in.], 150 mm [6 in.], 200 mm [8 in.], and 250 mm [10 in.]) were tested to determine their structural behavior when subjected to static loading and reloading conditions. Pull‐out and bending tests were performed on joints under buried, semiburied, and unburied conditions. The linear and nonlinear behavior of the joints was observed, including large joint displacements and joint slippage. Graphs of the pull‐out force versus joint displacement and of bending moment versus joint rotation were drawn based on test data. Analysis of the data on pull‐out tests showed a common pattern, as did that on bending tests.
