在前人對等截面、變截面實腹箱梁剪力滯效應影響參數研究的基礎上,本文進一步對腹板開孔的連續箱梁的寬跨比、底板翼緣伸出以及預應力錨固位置改變等參數對箱梁剪力滯的影響進行研究。As is well known, the effective width depends on several factors, such as the cross - section width, the height of web, the spacing of span and so on. we can conclude that width / span ratio ( overhang width / span and central width / span ) is the governing factor of the effective width
影響箱形截面樑上翼緣有效寬度的因素很多,如上翼緣寬度、梁高、跨度以及結構體系等,通過大量計算表明寬跨比[翼緣部分寬度、箱室部分寬度與跨度的比值]是有效寬度的控制影響因素。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
目前許多國家對于鋼結構箱形樑上翼緣有效寬度的取值都沒有明確規定,尤其是曲線梁橋由於其有效寬度的取值受曲線半徑的影響,其結構更趨復雜。This variation of stresses is due to the action of in - plane shear strain in the plate, which is termed “ shear - lag ”. stresses larger than the elementary bending uniform stress thus develop at the web - flange connection. an appropriate reduced “ effective width ” of the plate - with the uniform stress equal to the maximum longitudinal stress - has been widely used by engineers in conjunction with the elementary beam bending theory
但實際上翼緣中剪切變形是不均勻的,由此導致正應力沿橋寬呈曲線分佈,從而引出了有效寬度的概念,即按初等梁理論的公式也能得與真實應力峰值接近相等的那個翼緣折算寬度。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
按照初等梁理論即假定翼緣板具有無限抗剪剛度,寬翼緣箱梁在荷載作用下翼緣的正應力沿著寬度方向上是均勻分佈的。Analysis of flange effective distribution width of new type of gfrp composite beam
