| 摘 要： | 文章根据分离体挠曲变形协调,建立界面切向力与法向力的关系方程;联立界面连接件的剪力滑移物理方程,解得界面切向剪力、法向力及滑移的分布函数,进而导出组合梁挠曲线方程和附加挠度计算公式。算例显示均布荷载简支梁界面切向剪力或滑移自跨中向梁端呈近似线性分布,在合理连接度和外荷载下的附加挠度介于5%~13%,也小于规范方法的计算挠度。

| Abstract: | The relative equation of interface forces in tangential and normal directions is established on the basis of the flexural deformation compatibility of the separated units.The distributing functions of interface forces and slippage are gained based on the shear force-slip constitutive relation and the above relative equation.Then the deflection curve equation and the formula of additive deflection of composite beams are deduced.A calculation example is presented.It is found out that from the center to the ends of the beam the interface tangential force or slip in the simply supported beam under uniform loading show an approximately linear distribution,and that when the connecting degree and the loading are in the reasonable range,the additive deflection is between 5% and 13%,which is less than that obtained according to the related standard. |
