Steel bridge connecting plate bolt loosening monitoring point design method and system

The invention discloses a steel bridge connecting plate bolt loosening monitoring point design method and system. The system comprises an area setting module and a point design module. Firstly, the area setting module can adopt a manual mode to preliminarily set a layout area of monitoring point positions on a steel bridge connecting plate; or the stress distribution condition of the bolts on the steel bridge connecting plate can be analyzed through a finite element analysis method, and the area with the large stress is determined to serve as the arrangement area. Therefore, the number of subsequent schemes participating in deduction can be reduced, and the scheme design efficiency is improved. And then, the point location design module can perform deduction on each design scheme by adopting a Monte Carlo method, and an optimal layout scheme meeting design requirements is selected from numerous randomly generated monitoring point location layout schemes. 本发明公开了一种钢桥连接板螺栓松动监测点位设计方法及系统，系统包括区域设定模块和点位设计模块。首先，区域设定模
