中文摘要: |
应用子域加权残数法分析了曲线桥的内力,它拓宽了加权残数法的应用范围。对可比拟为正交异性曲板的曲线梁桥,用本法解决了任意点内力影响场问题,这为按影响场法设计曲线梁挢开辟了一条求解内力的新途径。最后给出了一个具体算例。 |
英文摘要: |
By making use of subdomain weighted residuals method, the internal forces of curved multi-girder bridge is analysed in this paper. It widens the applicable region for the general method of weighted residuals. For curved multi-girder bridge simulated as an orthotropic sector plate, this methodcan solve the influence fields of internal forces, and give a different way for the analysis of curved multi-girder bridge designed with the method of influence fields. Finally, a numerical example is presented. |
