A program has been developed to solve the mathematical model problem with software LINGO. The result shows that the optimization design program can be applied to design calculation of high-strength bolts connection, and the specification and the number of required hiGh-strength bolts can also be determined only by single-time calculation.Keywords:high-strength bolts connection; optimization design; 0-1 integer programming; control variable作者简介:刘迎春,讲师,博士研究生,Email:welspring@126.com。参考文献[1]曾元和,张效勤,等.宝钢厂房钢结构高强螺栓及其连接长期工作状况[J].工业建筑,1996,26(10):53-57.[2]吴福生.南浦大桥主桥结合梁高强螺栓施工[J].桥梁建设,1992(3):54-57.[3]李启才,顾强,等.摩擦型高强螺栓连接性能的试验研究[J].西安科技学院学报,2003,23(3):322-324.[4]徐娟,时旭东.摩擦型高强螺栓抗剪连接的螺栓单排数量和间距因素分析[J].施工技术,2006(5):74-76.[5]徐湘涛,范涛.普通螺栓群弯矩受拉中和轴位置分析[J].四川建筑科学研究,2006,32(1):66-68.[6]高轩能.偏心受拉普通螺栓群连接的合理计算[J].南昌大学学报(工科版),1996,18(4):17-21.[7]薛毅.数学建模基础[M].北京:北京工业大学出版社,2004.[8]钟善桐.钢结构[M].北京:中国建筑工业出版社,1988.
