  文摘:首先建立了下风侧附加翼板桥梁主梁截面的自激气动力模型。
• - ii - 5 . with the consideration that the cross section of the cable - stayed structure and the rigid frame structure ' s are not uniform , a new joint solution was presented for these different sections
  5 、针对金马大桥斜拉桥侧主梁截面与t构侧主梁截面形式不统一的问题，提出了一种不同结构断面的新型连接方法。
• Taking advantage of both , this paper choose t cross - section and enlarge detail dimension . the goal of optimum design is to increase torsion inertia moment and reduce shearing stress when moment of flexion and shear bearing capacity of single - beam is satisfied
  综合二者之优缺点，本课题选取t梁截面形式，用增大其细部尺寸的方法，以提高抗扭承载力为目标，满足弯剪等承载力要求为约束条件进行主梁截面的优化。
• The main shuchural features of the new electric single - girder overhead travelling crane presented in this paper is as follows : using a special gisder section to provide simple production technology and light weight ; dopting hinged connection at one end between main glrders and end carrages instead of the rigid connection at both ends , eliminating the three - point supporting problem with the crane and thus improving the travelling perfomance ; extending crane wheels life contributed to the combination of no - flange crane wheels and horizontal rollers
  提供种生产工艺简单、自重轻的主梁截面，并将单梁起重机主、端梁的刚性连接改为端用铰接连接，解决了在制造和轨道安装时因误差而造成的大车运行三条腿现象，提高了运行性能；用可调大车运行水平轮中心距的设计，代替带轮缘的大车轮，提高大车轮的使用寿命。

• Reasons : firstly , sectional dimension is so little that torsional stiffness of single - beam is n ' t enough . secondly , protective layer thickness is too thin to protect concrete reinforced bar and reduce durability . lastly , each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
  桥梁局部损坏较严重，主要原因是主梁截面尺寸过小、肋板过于薄弱，造成单梁抗扭刚度不足；保护层厚度不够导致钢筋外露引起锈蚀，降低了桥梁的耐久性；各主梁采用横隔梁连接成整体，横隔梁的刚度越大，桥梁的整体性越好，但调查结果显示，实际情况中并不能达到理想的整体刚度。
