GFRP-十字形钢骨混凝土柱轴压试验及力学性能研究
Research on axial compression test and mechanical properties of GFRP-cross-shaped steel-reinforced concrete columns
摘要
Abstract
The purpose of this paper is to study the mechanical properties of fiber reinforced composite(GFRP)steel reinforced concrete short columns under axial compression.The axial compression tests of 6 GFRP tubular steel-reinforced concrete short columns with different combinations were carried out,and the mechanical model of GFRP tubular cross-shaped steel-reinforced concrete columns was established by ABAQUS for parameter analysis.The effects of different section forms,web spacing,slenderness ratio and fiber winding angle on the axial compressive properties of the member are studied.The test results show that the ultimate bearing capacity of the new steel rein-forced concrete column with stiffening ribs is about 6%higher than that of the traditional steel reinforced concrete column.The ultimate bearing capacity of composite columns increases significantly with the increase of the spacing between steel webs.With the increase of slenderness ratio,the ultimate bearing capacity and stiffness of composite column decrease.The ultimate bearing capacity of the member with a single-layer fiber winding angle of 0° is 39%higher than that of the member with a fiber winding angle of 45°,but the initial stiffness of the member has little effect.At the same time,the ultimate bearing capacity and stiffness of alternately arranged fiber winding angle have no obvious change law.关键词
