摘要:
为套管加强梁腹板开孔梁柱节点的后续研究.运用ABAQUS有限元软件分析了腹板开孔梁段和套管加强H型钢梁腹板开孔梁段在弯矩、剪力及弯剪联合作用下的应力分布规律,发现套管对截面抗弯能力提高不大,但对截面抗剪承载力有大幅度的提高.文章结论给出了以开孔率和套管厚度为参数的截面抗弯、抗剪承载力公式及弯-剪相关公式.
Abstract:
The paper is a follow-up research of reduced beam section connections with stub tube reinforced web opening. The ABAQUS finite element software is used to analyze the static behavior of short beams with web opening and short beams with stub tube reinforced web opening, under bending, shearing and combined action. It is demonstrated that stub tubes can significantly increase the shear resistance of the short beam, while just a little improvement is recorded in moment resistance. Based on the FEM results, formulas considering opening ratio and thickness of the stub tube for predicting the bending, shearing and combined strength of short beams with stub tube reinforced web opening are proposed.
