摘要:
为研究钢箱系杆拱桥应力集中节点在高速铁路荷载下的疲劳性能，本文依托某高速铁路钢箱系杆拱桥工程，采用有限元软件ANSYS建立全桥简化模型，并对两处应力极值位置建立精细化局部模型。通过规范评价和疲劳理论评价对精细化局部模型中应力集中节点进行了疲劳分析。研究结果表明本桥各应力节点均满足疲劳性要求，且评价结果远优于限值。
Abstract:
To investigate the fatigue performance of stress concentrated joints in a steel box-tied arch bridge under high-speed railway load，this study employed a simplified full-bridge model created using the finite element software ANSYS，based on a specific high-speed railway steel box-tied arch bridge project. Further，detailed local models were established at two locations with maximum stress values for thorough analysis. Both code-based evaluation and theoretical fatigue assessments were conducted on the stress concentrated joints within the refined local models. The results demonstrate that all stressed joints in the bridge meet the required fatigue criteria，with the assessment outcomes significantly exceeding the limiting values.
