单箱三室箱梁动力特性分析
The dynamic-property analysis of single-box three-cell girder
摘要
Abstract
A unified analytical beam model and a finite nodal-line method are employed to analyze the dynamic properties of a single-box three-cell girder,for the purpose of computing the first three order vibration frequencies and vibration modes and the investigation into the vibration characteristics of the girder,with the help of the diagrams of top flange vibration modes.Computational results show that the vibration in the non-symmetric-axis direction of the girder are coupled together with the torsional vibration of the cross section.关键词
