摘要
以某108 m钢桁梁桥为工程背景,采用有限元分析软件MIDAS/CIVIL建立全桥模型,与施工中的实测数据进行对比;采用有限元软件ANSYS建立上弦杆整体节点A5模型并与实测数据相比,验证了模型的准确性.研究了拼接位置分别为3、3.98、6 m的整体节点的受力性能,结果表明:整体节点体系变形最大的位置发生在拼接缝处,拼接位置越靠近整体节点,拼接板的受力和变形越小.研究结果可为工程设计及实践提供指导.
Abstract
Taking a 108 m steel truss bridge as the engineering background,the finite element analysis software MIDAS/CIVIL was used to establish the full bridge model and compare with the measured data during construction.ANSYS finite element software was used to establish the upper chord integral node A5 model,and the calculated results of the model were compared with the measured data to verify the accuracy of the model.The stress performance of the integral nodes with splice positions of 3 m,3.98 m and 6 m was studied.The results show that the largest deformation of the integral node system occurs at the splice joint.The closer the splice position is to the integral node,the smaller the force and deformation of the splice plate.The results can provide guidance for engineering design and practice.
