【摘要】 以国内某大跨径斜拉桥为例,通过有限元软件ANSYS采用子模型技术法、等效板厚法及非线性接触法对大跨径斜拉桥索梁锚固区应力分布进行分析。结果表明,相比于传统的等效板厚法及非线性接触法,子模型技术法计算更精细、准确,是研究大跨径斜拉桥索梁锚固区应力分布的最有效方法。更多还原

【Abstract】 Based on a domestic long span cable-stayed bridge as an example,using the finite element software ANSYS,the stress distribution of the bridge anchorage zone was studied respectively by sub-modeling method, equivalent thickness method and nonlinear contact method.The result shows that the sub-modeling method is more accurate compared to the traditional equivalent thickness method and nonlinear contact method,and is the most effective method in studying local stress distribution of the anchorage zone of long span cable-stayed bridge.更多还原
