Title
(EN) An improved beam
(ZH) 一种改进的梁
front page image
Abstract
(EN) The present invention provides a hollow flange channel beam having a planar web with a pair of narrow rectangular cross-section flanges extending along opposite sides of said web and extending perpendicular to a face of said web in the same direction. The section is optimised when Wf =(0.3)Db, Wf=(3.0)Df and WF=(30)t.
(ZH)

一种改进的梁，包括具有平面梁腹板的空心翼缘槽形梁，并且一对窄矩形横截面的翼缘沿所述梁腹板的相反侧面延伸并且垂直于所述梁腹板的一个表面沿相同的方向延伸。当Wf＝(0.3)Db，Wf＝(3.0)Df和Wf＝(30)t时所述截面最优化。
