<p>A structural system for use in bridges, buildings and other structures. The system solves the problem of spanning a distance between two points by providing a bridge which supports part of its load by tension action and part of its load by arch action. Cables (21) are stretched and anchored between end supports (20). Lateral compressive elements (22) are placed over the cables which fit in grooves (26) across the bottoms of the elements. The grooves vary in depth. The cables are near the bottom of the elements at the center span and near the top of the elements at the end supports.</p> |
