摘要
基于费氏空腹桁架理论,建立了剪力键式钢空腹梁内力及变形简化计算方法.通过精细化有限元方法分析了三种不同节点形式剪力键式空腹梁的内力及变形分布规律、影响因素,并与简化计算方法进行对比.分析表明:设置加劲肋可以显著改善空腹梁的内力及变形特征;挠度简化计算方法能准确反映设置加劲肋的空腹梁变形特征;修正后的应力计算方法可以用于工程实践.
This paper presents a new simplified calculation method. The method is based on the theory of Atlftlish vierendeel truss. Analyzes the internal force and Deformation of vierendeel beam with three kinds of connections. Compare the value calculated by finite element method and by simplified calculation method. The analysis shows that the ribbed stiffener is important to internal force and deformation of vierendeel beam. The revised simplified calculation method can convey accurate signals of internal force and deformation.
