| 中文摘要: |
| 销连接是现代钢结构连接常用的形式，然而销孔与销轴之间不可避免地存在间隙。利用ANSYS软件研究销孔间隙对耳板孔壁承压容许应力的影响。在弹塑性阶段，通过详细的数值分析以塑性区面积为“桥梁”研究了销孔间隙对耳板孔壁承压建议容许应力的影响。将得到的离散数据进行解析拟合，给出了耳板承压建议容许应力随销孔间隙变化的公式。 |

| Pin connection is commonly used in modern steel structure connection. However, there is an inevitable clearance between the pin shaft and the pin hole. This paper studies the pin hole clearance effects on the ear plate hole wall allowable bearing stress by ANSYS software. In the plastic stage, the pin hole clearance effects on the plate hole bearing allowable stress is studied with the the plastic area as "bridge" and through detailed numerical analyses. The discrete data are fitted to obtain a formula about the plate bearing allowable stress with the pin hole clearance. |
