销轴在竖向荷载作用下的受力与变形分析

An Analysis of Stress and Deformation of the Pin under Vertical Loads

销轴连接在建筑中的应用日益增多,可靠合理的设计为其安全使用提供依据和保障。考虑到销轴在整个传力过程中的过渡作用至关重要,文章重点分析了承受竖向荷载的销轴在弹性、弹塑性阶段的受力与变形。结果表明,按文章中的分析方法计算得到的销轴在弹性与弹塑性段的受力与变形,与其他文献中的试验实测值和有限元模拟值具有一致性。

With the pin connection being widely used in construction industry,reliable and reasonable design will ensure the safety of pin application.Based on the significant role the pin play in the process of force transmission,the authors of this paper have made a study of the stress and deformation of the pin which bears the vertical loads in the elastic and elasticplastic stages.The results show that the stress and deformation of the pin in the elastic and elastic-plastic stages,obtained with the analysis method described in this paper,are consistent with the measured values in the other literature and those obtained by the finite element simulation.
