Fatigue S-N curves of bolts and bolted connections for application in civil engineering structures

Bolts and bolted connections are frequently used in civil engineering steel structures. This paper presents a meta study where a few thousand fatigue tests on these elements are evaluated. The evaluation reveals that current specifications in design standards need updating to account for the relevant stress parameter and production methods. This substantially reduces the scatter of the fatigue resistance. The shape and position of the fatigue resistance (S-N) curves also require updating. The results of this study have been implemented in the new revision of European standard EN 1993-1-9. This paper provides the background for the modifications.

用于土木工程结构的螺栓和螺栓连接的疲劳 SN 曲线

螺栓和螺栓连接在土木工程钢结构中经常使用。本文介绍了一项元研究,其中评估了对这些元素的数千次疲劳测试。评估表明,设计标准中的当前规范需要更新,以考虑相关的应力参数和生产方法。这大大减少了疲劳强度的分散。疲劳抗力 (SN) 曲线的形状和位置也需要更新。这项研究的结果已在新修订的欧洲标准 EN 1993-1-9 中实施。本文提供了修改的背景。
