摘要
桁式组合拱桥在进行活载冲击系数计算时,即有桁式组合拱桥计算时未考虑冲击效应的影响。以桁式组合拱桥花鱼洞大桥检测结果为分析研究对象,分析其在汽车荷载作用下的冲击效应。通过对该类桥型动测书籍分析认为该类桥型动力冲击效应明显,实际计算中应计算其冲击系数对该类结构的影响。
Truss Arch Bridge during live load impact factor calculation,the existing Truss Arch Bridge calculation that does not take into account the impact effects.The existing Truss Bridge Arch Bridge Flower Yudong object is studied for the analysis of test results to analyze its in the car loads of knock-on effects. Through that type of dynamic testing of bridge-type books,analysts believe that such effects are more obvious impact of the bridge-type power.The actual calculation of the impact factor should be calculated for that type of structure.
