摘要:
为研究管厚对GFRP管构件的应力及变形的影响规律,利用有限元软件ANSYS,建立GFRP管约束型钢混凝土柱模型,并运用等效应力云图、极限承载力试验、荷载-变形曲线进行分析.研究结果表明:壁厚越大,延性越好,对组合柱核心混凝土的约束作用越强; 随管厚增大,承载力提升幅度也增大; 管厚取6~7 mm为宜.
Abstract:
In order to study the effect of tube thickness on the stress and deformation of GFRP pipe members,the finite element software ANSYS was used to establish the model of confined steel reinforced concrete columns with GFRP pipe.The equivalent stress nephogram,ultimate bearing capacity test and load-deformation curve was used to analyze the model.The results show that the bigger the wall thickness is,the better the ductility is,and the stronger the restraint effect on the core concrete of composite columns; with the increase of the pipe thickness,the increase of the bearing capacity is also increased; the appropriate thickness of the pipe is 6-7 mm.
