摘　　要：针对当前土建工程上广泛应用的变截面梁桥,在移动车辆作用下动力响应的解析解难以得到,基于有限单元法的基本思想,利用Fortran语言强大的计算功能采用数值计算方法模拟在移动荷载作用下梁桥的振动情况,同时结合VisualBasic语言良好的可视化界面设计功能,开发出能计算复杂工况且具有较好的人机交互界面的桥梁动力计算软件,实现了VB的可视化界面与For-tran强大的数值计算能力的结合。In allusion to the problem that for comprehensive application of non-uniform section beam in bridge engineering at present, it is difficult to get an analytical solution of dynamics response under the force of moving vehicle, a bridge dynamics calculation software with good human-machine interactive interface and capable of calculating complex working condition is developed. It adopts numerical method and uses powerful computing function of Fortran language to simulate the vibration circumstances of beam under the moving loads based on the finite el- ement method, and combines at the same time with good visualisation interface design function of Visual Basic language. The software realises the combination of the visualisation interface of VB and the powerful numerical computing ability of Fortran.
