TENSIONING AIR BEAM SYSTEM WITH CURVED TYPE LOWER AND UPPER CHORD MEMBERS, CAPABLE OF EFFECTIVELY RESISTING TO REPEATED LOAD AND BIDIRECTIONAL LOAD OF A TENSILE SIDE AND A COMPRESSION SIDE

摘要

PURPOSE: A tensioning air beam system with curved type lower and upper chord members is provided to be effective to a continuous beam by delivering tensile force caused by a cable to upper and lower steel materials, and to strengthen resistance properties against bending moment.;CONSTITUTION: A tensioning air beam system comprises an upper chord member(10a), a lower chord member(10b), an air tube(20), an end anchorage, a center anchorage, and a cable. The air tube is tapered and separately has the upper and lower chord members at the upper and lower ends. The upper and lower chord members are curved to narrow the space between the two chord members from the center towards both ends by corresponding to the shape of the air tube. Both sides of the upper and lower chord members in the longitudinal direction are fixed with the end and center anchorages. The end and center anchorages are fixed on both longitudinal lateral sides of the upper and lower chord members. The cable is tensely anchored to the end anchorage by passing through the center anchorage.;COPYRIGHT KIPO 2013
