cell box girder meaning in Chinese
多孔箱形梁
Examples
- Each bundle of strands is connected to one side of the center web of the two cell box girder .
每束钢缆锚固在双箱梁的中间腹板的一侧。 - Multi - cell box girder
多孔箱形梁 - Based on the minimum potential energy principal , the influences of three loads , which are concentrated force , trapezoidal load and sinusoid load , over shear lag of cantilever single - box - single - cell box girder are deducted and discussed , and a conclusion is reached , which has some instructive significance for designer to determine the sectional dimension and reinforcing bars ; the bending normal stress changes greatly as considering the shear lag effect
以最小势能原理为基础，推导并讨论了3种形式的荷载：集中力、梯形荷载、正弦形荷载对悬臂单箱单室箱形梁剪力滞的影响，得出考虑剪力滞效应后弯曲法向应力有较大变化的结论，对设计人员确定截面尺寸、截面配筋具有一定的指导意义。 - 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。 - There are two contents in this paper : one is solve the control differential equation of box girder " s shear lag by dq method , the other is rules of the shear lag for single - box - multiple - cell box girders . first we introduce what is shear lag and the status of research ; we introduce dq method and use dq method to solve several bridges in the third chapter ; also we introduce the software - ansys and analysis several bridges by ansys in chapter iii ; in chapter iv we assume several bridge models and get the stress distribution under concentrated load and distributed load ; we summarize the paper in chapter v and propose the advancing direction of shear lag
文章首先介绍了剪力滞定义及目前研究情况；第三章介绍了dq法以及用dq法解箱梁剪力滞控制微分方程的几个实例，说明了dq法在求解变截面箱梁剪力滞中的优势；第四章介绍了有限元软件ansys ，以及用ansys分析桥梁受力情况的几个例子，说明了用ansys中相关单元分析桥梁的可行性：第五章构造单箱双室、三室、四室的悬臂梁、简支梁模型，分别分析了他们在集中荷载、均布荷载作用下的受力情况。
