DEVICE FOR PROTECTION OF BRIDGE FROM SIDE WIND Russian patent published in 1998 - IPC

FIELD: designs of bridges, more specifically, protection of bridges from side wind causing its failure. SUBSTANCE: device includes bridge on piers and provided with automatic control device which consists of sails accumulating wind energy and located on guides for displacement along them. Each end of sail accumulating wind energy is tied to unequal-arm lever located on fixed pier, while the other end, is connected by means of controlling rope, respectively, with bridge framework. Sails accumulating with energy are located, either, in bridge middle part or on bridge in several points, or on both sides of bridge on the water reservoir bank in at least four points. EFFECT: simplified automation of device controlling bridge deformation caused by side wind due to utilization of wind force and simple mechanical appliances, and higher reliability of bridge stability under effect of side wind (or blast wave). 6 dwg
