Abstract

A crossbeam with tubular structure includes a planarly-extended web plate and a pair of narrow flanges with a rectangular cross-section, and is perpendicular to a plane formed by extension of the two sides of the web plate on the opposite side of the flanges. The cross-section volume with an optimum efficiency is: Wf=(0.3)Db, Wf=(3.0)Df, and Wf=(30)t, in which Wf = the width of flange, Db = depth of crossbeam, and Df = depth of flange, and t = thickness of steel plate formed a hollow flange tube. Based on each weight/meter basis, the invented crossbeam has a better cross-section efficiency than a hot-rolled or a cold-rolled one, and has a better connection property than a hot-rolled or a conventional hollow flange crossbeam.
