基于AUTO CAD二次开发技术的主梁解体高强度螺栓组计算程序的开发

Development of calculation program for high-strength bolt set in girder disassembly based on AUTO CAD secondary development technology

以Visual Basic为工具,采用AUTO CAD二次开发技术,提取桥、门式起重机主梁解体处法兰板截面的有用信息,分别计算翼缘板螺栓组和腹板螺栓组承受的主梁弯矩和剪力,进而对主梁解体处高强度螺栓组进行校核计算。

AUTO CAD secondary development technology is adopted for collection of useful information regarding flange plate sections at the girder disassembly location of bridge cranes and gantry cranes with Visual Basic, and respective calculation of the bending moment and shearing force of flange plate and web bolt sets, realizing check calculation for the high-strength bolt set at girder disassembly location.
