Abstract
A structure that creates a compressive mechanical lock during an external force includes a beam, an offset bulkhead, and a compressive member. The beam has a hollow cross section, an axis, and a wall. The bulkhead is disposed within the hollow cross section and attached to the wall. The member has an axis and an end attached to one of the bulkhead and the beam wall. The member axis and the beam axis intersect with each other in a plan view to form an obtuse angle. The bulkhead is offset from the intersection in an offset direction, parallel to the beam axis and toward the opening of the obtuse angle. The external force causes the member end to deform the beam wall so as to create a pocket or compressive mechanical lock in the beam wall that mechanically locks the member end from moving in the offset direction.
