Finite Element Analysis on Hole Radius of Circular-Web Opening Steel Beams

钢结构住宅中开孔梁的研究应用是一个重要的课题.影响圆形开孔梁性能的参数很多,其中开孔半径r是重要的影响参数之一.主要就开孔半径进行了有限元分析,研究了开孔半径影响圆形开孔梁受力性能的变化规律,并得出了此参数的建议取值范围,为圆形开孔梁的工业化生产提供了可靠依据.

In the steel structure housing, the research and application of web-opening steel beams has been an important topic. Many parameters effect behaviors of web-opening steel beams. And the opening radius is significant one of these parameters. In this paper, opening radius has been analyzed by means of the finite element analysis. The working law of the web-opening steel beams influenced by opening radius has been studied and the value range of opening radius has also been given. The analysis results provide reliable references for the industrial production of web-round opening steel beams.
