Abstract
A corrugated panel structure for supporting compressive loads includes curved cap strips 22 separated by truss-core web segments 30. The truss-core web segments 30 are formed from first and second flat panels 32 and 34 with a corrugated filler 36 therebetween. The corrugated filler 36 extends in the direction of the compressive load, thereby providing load carrying capability for the compressive load. As a result, all components of the panel structure have a compressive load carrying capability resulting in a high strength-to-weight ratio when the compressive load is limiting.

A corrugated panel structure for supporting a compressive load in a length direction, comprising:
- cap strips extending in the length direction, having a curved cross-section;
- and
- truss-core web segments, bonded to and separating said cap strips in an open cross-section arrangement each truss-core web segment having a sandwich construction, including first and second flat panels parallel to the length direction and a corrugated filler, bonded between said first and second flat panels, extending in the length direction with a non-linear cross-section.
A corrugated panel structure for supporting a compressive load in a length direction, comprising:
- cap strips extending in the length direction, having a curved cross-section with an apex;
- and
- truss-core web segments, bonded to and separating said cap strips, the apex of the curved cross-section of each of said cap strips being formed between two of said truss-core web segments, each of said truss-core web segments having a sandwich construction, including first and second flat panels parallel to the length direction and a corrugated filler, bonded between said first and second flat panels, extending in the length direction with a non-linear cross-section.
