The width of web plate of two pieces beam is 14cm and another two is 16cm . the paper consists of five chapters . of these chapters , chapters two , three and four are kernels 同时用弹性力学原理研究了宽翼缘梁的剪力滞效应,为今后的设计以及桥梁质量控制、维修加固提供了参考。
However , the stud welding roots in the negative moment region of the beam are often subjected to the joint action of shear stress cycling of the studs and tensile stress cycling of steel girder flanges 但在负弯矩处栓钉焊趾往往承受栓钉剪应力循环和钢梁翼缘拉应力循环的共同作用。
In the design of steel - concrete composite beams , shear lageffects considered , the effect flange width concept is used to analyze the defections and stresses of beams 摘要在进行钢混凝土组合梁设计分析时，考虑到剪力滞效应的影响，常采用翼缘有效宽度的概念计算组合结构的应力和变形。
The form of variable cross - section , used mostly in the practical projects , just has the change of the linear variation on the height of the web plate while keep the width of the flange c hangeless 实际工程中使用最多的变截面构件形式是仅构件腹板高度线性变化，翼缘宽度保持不变的形式。
In elementary beam bending theory , it is assumed that the stresses are constant through the width of the beam . however , for the wide flange girders , the stresses are not uniform 按照初等梁理论即假定翼缘板具有无限抗剪刚度,宽翼缘箱梁在荷载作用下翼缘的正应力沿着宽度方向上是均匀分布的。
Two hypothesises , different from the traditional viewpoints , about stress distribution in beam section at the connection of beam and end - plate are presented by author to determine the ultimate moment of end - plate connection 其计算过程分为两步： ( 1 )计算梁受拉翼缘的极限拉力； ( 2 )计算端板连接的极限弯矩。
This paper researches the plane stiffness of new composite structure for slab on the lower flange , which is compared with the traditional structure for the slab on the top flange 本文研究了将楼板置于钢梁下翼缘的新型组合结构平面刚度，并和传统的将楼板置于钢梁上翼缘的结构形式的平面刚度和极限承载力作了比较。
Through comparison of the effect flange width provisions between several countries , points out the basic factors affected the effective flange width and the shortcomings of chinese code 就国内外不同规范对翼缘有效宽度的规定进行了比较，指出了影响翼缘有效宽度的基本因素，阐明了我国规范和其他规范的差别，以及我国规范的不足之处。
Integral stability capacity of rolled beam is more 10 % ~ 20 % than welded beam . at the same time , the inelastic integral stability capacity of wild rolled h - section ( hw ) steel beam is more superior observably than hn steel beam 弹塑性稳定范围，轧制梁比焊接梁大约多10 20的安全储备，且宽翼缘轧制h型钢的整体稳定性能高于窄翼缘轧制h型钢。
There are not definite code provision of evaluation of effective width about steel box - girder in many countries , especially curved bridge because its evaluation of effective width vary with the radius of the curve 目前许多国家对于钢结构箱形梁上翼缘有效宽度的取值都没有明确规定,尤其是曲线梁桥由于其有效宽度的取值受曲线半径的影响,其结构更趋复杂。
