girder section
Examples
- Abstract : a model of self - excited ae rodynamic forces acting on a sectionof bridge deck with additional surface atta ched below the trailing edge is established
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。 - The work in this thesis mainly includes following parts : 1 . as for box girder cross section , the three - bar stimulation method under typical loads and supports has been introduced . the force and stress formulae for flanges have been derived from the three - bar method . by reasonable simplification for multi - cell box girder , the three - bar method has been applied in multi - cell box girder ' s shear lag analysis
对于箱形截面主梁，本文介绍了三杆比拟法上、下翼板中比拟杆的计算公式，以及在典型荷载和支承的情况下翼板内各杆的应力计算公式，并对多箱式主梁截面进行合理简化，使三杆比拟法应用于多室箱梁的剪力滞分析。
