钢结构桥梁的横向载荷应力试验研究

Experimental Study on Lateral Load Stress of Steel Structure Bridges

为探究钢结构桥梁所承受的横向载荷应力及影响因素,将以桥梁所承受的应力为基础探究在该环境下桥梁的横向载荷应力变化。从钢结构桥梁的抗疲劳设计角度出发明确常规的抗疲劳设计方法,通过对关键点的分析为实验设计奠定基础,利用实验设计得到影响桥梁横向应力变化的因素。实验结果表明:钢结构的几何尺寸、焊接、受力方式和受力点的分布均会直接影响结构的应力水平,应当加强该方面的管理以提高钢结构桥梁的结构稳定性。

In order to explore the lateral load stress and influencing factors of steel structure bridges,the lateral load stress changes of bridges in this environment will be explored based on the stress of bridges.From the perspective of anti-fatigue design of steel structure bridges,the conventional anti-fatigue design method is clarified,and the analysis of key points lays the foundation for the experimental design,and the factors affecting the lateral stress change of the bridge are obtained by using the experimental design.The experimental results show that the geometric size,welding,stress mode and distribution of stress points of the steel structure will directly affect the stress level of the structure,and the management of this aspect should be strengthened to improve the structural stability of the steel structure bridge.
