A versatile experimental setup was recently built at the University of Ottawa Structural Laboratory with the capability of testing full-scale pipes under load combinations involving axial tensile/compressive force, twist, shear, internal pressure, and imposed bending deformations. This paper presents the innovative aspects of the new experimental setup and documents some aspects of the deformational behavior of pipe specimen of X65 material, 20 in. OD with a diameter to thickness ratio of 80, under the combined action of internal pressure, axial tensile force, torsion, and imposed curvature, which was recently conducted under the new setup. The results reported are part of a testing program, which is currently underway.
