摘要
使用ANSYS有限元分析软件,对外包U型钢-混凝土组合梁有效翼缘宽度的取值进行了研究。在采用静力等效原则的基础上,通过参数化分析,研究了宽跨比、荷载形式、混凝土板厚、材料强度等因素对组合梁有效翼缘宽度取值的影响,总结了有效翼缘宽度随荷载变化的一般规律。分析结果表明荷载形式和宽跨比对有效翼缘宽度的取值影响明显,通过数据回归提出了相应的计算公式。
This paper analyzes the effective flange width of U-section steel-encased concrete composite beam with ANSYS. On the basis of using the static equivalent principle,the parametric analysis of width-span ratio,loading form,thickness of concrete slab,strength of materials and other factors are carried out to study the influence on the effective flange width,and the general rule of the effective flange width varying with load is summarized. The results show that the loading form and the width-span ratio influence the effective width significantly. The regressive formulas are suggested based on these results.
