摘　　要：前期研究提出的GFRP筋混凝土桥面板基于拱效应下的设计方法,其计算过程较繁琐。采用Visual Basic语言把设计方法编写成人机交互式的设计软件,可提高设计工作效率。当用户输入几何数据、材料的物理力学性能及荷载条件,软件即可自动计算面板的正常使用极限荷载和承载力极限荷载,获得GFRP筋混凝土桥面板的设计承载力。不同荷载值下的变形、裂缝宽度及拱推力大小等其他计算结果可以启动查询窗口查看。软件操作过程保持与原设计思路一致,软件界面沿用windows系统软件的风格,使软件易于理解和掌握。Design method of concrete bridge deck reinforced with GFRP bars based on arching action is proposed during the previous studies , but calculation process of the method is rather complicated .Using Visual Basic language to develop interactive de-sign software on the design method can improve efficiency of design work .When users input the geometric data , physical and me-chanical properties of materials , and loading conditions , serviceability ultimate load and bearing capacity load can be automatically calculated , and then design bearing capacity of GFRP reinforced concrete bridge deck is determined .Starting the query window , de-formation, crack width , arch thrust and other results under different loads can be queried .Software operation process is in keeping with the original design , and the interface style of the software is in agreement with the Windows system , which makes the operation easy to be understood and mastered .
