| 摘 要： | 以千米级3塔连跨悬索桥——泰州大桥为工程背景,比较了国内规范对加劲梁竖向挠跨比的相关规定,指出了该规定的实质目的是使行车平稳、安全.通过ANSYS有限元程序对比分析了泰州大桥4种汽车荷载典型工况下的整体位移,结果表明:加劲梁梁端竖向转角与加劲梁竖向挠跨比无本质联系(对于大跨度悬索桥)；加劲梁梁端竖向转角与中塔纵向抗弯刚...

| Abstract: | Based on the thousand-meter scale three-pylon continuous suspension bridge,Taizhou Bridge,the relevant regulations on vertical deflection-span ratio of stiffening girder stipulated in domestic codes and specifications were compared,which indicates that the essential objective of these regulations is to make vehicles travel stably and safely.By ANSYS finite element program,the ensemble displacements of Taizhou Bridge under four typical cases were comparatively analysed.The results show that that(1) there is ... |
