子模型技术在钢板梁桥应力分析中的应用

The application of sub-models technique in the analysis of stress in a steel plate girder bridge

简述了子模型的建立步骤,采用ANSYS计算了钢板梁桥的端连接板应力集中,并提出了一个新的验证切割边界合理性的方法,计算结果表明,钢板梁桥端连接板处有较高的应力集中现象。

The procedure of establishment of sub-model is briefly introduced. Using the ANSYS program, the stress concentration in the end connection plate of steel plate girder bridge is calculated, and a method is proposed to validate the rationality of selection of cutting boundary. According to the results of calculation, it has higher stress concentration in the end connection plates.
