| 摘要： | In recent years, Variable Message Sign (VMS) panels have become increasingly popular. The geometry of these signs sometimes results in significant cyclic loading of the support structure due to wind gusts. The wind gusts can result from passing trucks or from natural wind. The report covers analytical and experimental investigations of VMS structures in Birmingham and Mobile, Alabama. Commercially available software GTSTRUDL is used to perform space frame structural analyses of these welded tubular structures. Measurements from a static load test of the Birmingham structure are presented and compared to structural analysis results. |
