摘要
对某组合梁斜拉桥拉索锚拉板建立空间块体有限元模型进行局部应力分析,并与实测应力结果进行比较,验证模型的正确性。以此模型分析结构的应力分布规律,对最大索力值状态下的锚拉板应力进行验算与评估。
By establishing a space block finite element model, this paper analyzes the local stress of anchor pulling plate in stay cables of some composite beam cable-stayed bridge, and compares with the measured stress results to verify the correctness of the model. It also analyzes the stress distribution rules of structures based on this model, and performs the checking chor pulling plate in the state of the maximal cable force.
