ABSTRACT:
A braced girder for steel-reinforced concrete construction, comprising a top chord connection to two bottom chords by a continuous lacing which forms a repeating pattern consisting of braces which are at least roughly perpendicular to the top chord, and of diagonal braces. At least two braces in the continuous lacing are perpendicular to the chord and follow each other consecutively. The girder has a triangular cross section. Where the two panel planes meet, the lacing forms a radius which is at least 0.4 times the diameter of the top chord. A method and apparatus for preparing such a girder are also disclosed.
