Title:
STEEL STRUCTURE INCLUDING A PRE-STRESSING BRACKET FOR IMPROVING LOAD-CARRYING CAPACITY AND SERVICEABILITY
Document Type and Number:
WIPO Patent Application WO/2012/002642
Kind Code:
A3
Abstract:
The present invention relates to a steel structure including a pre-stressing bracket for improving load-carrying capacity and serviceability, and more particularly, to a steel structure including: a steel girder; a plurality of connecting brackets connected to the bottom surface of the steel girder, and spaced apart from one another; and a cover plate connected to the bottom surfaces of the connecting brackets. Accordingly, since the cover plate is installed regardless of the connecting portion of the steel girder, pre-stressing sections can be consecutively formed to improve the pre-stress effect. In addition, since the connecting brackets space the steel girder a constant distance from the cover plate, the second moment of area is increased to maximize area efficiency, thereby increasing the span of a bridge.
