System and Method for Loading a Test Asset

A test structure includes a frame, a shear reduction plate configured to couple to a first end of a test asset, and multiple rockers. Each rocker includes a first end that has a curved contact surface configured to contact the shear reduction plate and a second end having a connector movably coupled to the frame and configured to pivot, responsive to a bending moment applied to the test asset, such that the curved contact surface rocks in contact with the shear reduction plate.
