本文采用Abaqus有限元分析软件对开不同形状洞口的框支转换梁在竖向均布荷载作用下的受力情况进行了分析。探讨了不同形状的洞口对框支转换梁的应力分布规律以及洞口附近的应力变化情况的影响。分析结果表明,洞口的形状对应力的分布有不同的影响,剪应力分布不受洞口形状的影响。
In this paper, Abaqus finite element analysis software was used to analyze the force of box-girder conversion beam with different shape holes under vertical uniform load. The influence of different shapes of holes on the stress distribution and the stress changes around the hole are discussed. The analysis results show that the shape of the hole has different effects on the distribution of stress, and the distribution of the shear stress is not affected by the shape of the hole.
