中文摘要: 移动车辆通过变截面连续箱梁桥的动力响应一般采用有限元数值计算程序进行分析,但其前后处理界面和图形功能微弱.针对这一情况,提出了混合编程方法,把Fortran语言强大的计算功能和Visual Basic语言良好的可视化界面设计功能结合起来,开发了桥梁动力响应有限元计算程序系统.系统不仅能解决复杂的工程问题,并且具有较好的人机交互界面.对系统开发过程中混合编程方面遇到的疑难问题进行阐述,给出了相应的解决方法.
Abstract:The dynamic response of continuous box girder bridge when vehicle crossing was analyzed with a finite element calculation program. But the pre-post processing interface and graphic function are weak. In view of this, a mixed programming method was proposed by Fortran language with powerful computing function combined with Visual Basic language which has the good functions of visualization design. A finite element system for the calculation of bridge dynamic responseis worked out. This software not only can solve the complex engineering problems, but also has a good interactive interface. Some knotty problems encountered in the development process about mixed programming are described, and some corresponding solutions are given.
