混凝土简支T梁剪力滞效应研究

Study on Shear Lag Effect of Concrete Simply Supported T-beam

本文以某实际工程为例,利用ANSYS的有限元分析软件,建立分析模型,通过选取不同单元形式,对比得出剪力滞效应分别在均布荷载及集中荷载作用下的分布规律。通过改变T梁截面尺寸,探究了不同高跨比、宽跨比的情况下剪力滞系数的变化规律,对实际工作具有指导意义。

Taking a practical project as an example, this paper establishes the analysis model by using the finite element analysis software of ANSYS.By selecting different element forms, the distribution laws of shear lag effect under uniformly distributed load and concentrated load are compared and analyzed. By changing the section size of T-beam, the variation law of shear lag coefficient under different height-span ratio and width-span ratio is explored, which could provide reference for practical work.
