摘要
为研究横隔梁损伤对桥梁结构横向受力性能的影响,利用有限元软件ANSYS建立能够模拟横隔梁损伤桥梁横向受力的模型,分析各主梁横向影响线的变化.结果表明,横隔梁损伤会对桥梁结构横向受力造成不利的影响,其横向传递荷载的能力随损伤程度的加大而被减弱;且横隔梁损伤程度的大小直接影响各主梁所分配到的荷载;此外横隔梁的损伤会对不同位置的主梁产生不同程度的影响,距离损伤横隔梁越近的主梁,受到的影响越大.
To investigate the effect of diaphragm beam damage on the lateral mechanical the structural performance of the bridge,a model that can simulate the transverse force of the diaphragm damage bridge is established using the finite element software ANSYS to analyze the transverse influence line of each main beam.The results show that diaphragm damage will have a negative impact on the transverse force of the bridge structure,and its transverse transfer load ability is weakened with the increase of the damage degree.The damage degree of transverse beam directly affects the load assigned to each main girder.Simultaneously,after the diaphragm beam has been weakened,the greater the distance from the affected diaphragm beam,the less well connected with the surrounding girder,the worse the stress state of the main girder.
