摘要
利用通用有限元软件ANSYS对温度荷载作用下混凝土箱梁剪力滞后效应进行数值分析,其结果表明,温度作用下箱梁翼板与肋板交接处存在着较为严重的剪力滞后现象,并获得了箱梁在温度荷载作用下剪力滞后效应的一般规律和初步结论,为箱梁的温度应力计算提供了参考。
This paper research the concrete girders shear lag in numerical analysis by using general finite element software ANSYS.The results show that the wing plate and rib plate junction has serious shear lag phenomenon under temperature load and obtain the general rules of shear lag effect under temperature loads.The research provides the reference of the analysis with the shear lag of concrete girders under temperature load.
