带肋钢管混凝土轴压力学性能研究综述

Review of research on axial compressive properties of concrete-filled steel tube with ribs

我国的经济水平和科学技术都在飞速发展,建筑行业也是如此。在此基础上,人们对建筑的功能和外形提出了越来越高的要求,不断追求更丰富的构造形态和建筑功能。为了满足人们对建筑物更高层次的需求,达到建筑美观、结构合理的要求,采用普通的钢筋混凝土构件必然会出现梁、柱截面特别大的现象,影响建筑物的有效使用面积且缺乏美感。钢管混凝土这种复合构件因其较高的结构承载力、良好的抗震防火性能受到了广泛的关注,随着对这种结构的深入研究,研究人员发现,钢管与混凝土之间的滑移现象会影响构件的承载能力,为此,通过设置加劲肋改善其力学性能。因此,进一步研究带肋钢管混凝土的轴压性能对工程实际具有重要意义。

Our economy,living standards,science and technology have been developing rapidly,as is the construction industry.Base on this,human beings have put forward higher and higher requirements for the function and shape of buildings,and constantly pursue richer structural forms and architectural functions.n order to meet people's higher demand for buildings and meet the requirements of beautiful buildings and reasonable structures,the use of ordinary reinforced concrete members will inevitably lead to the phenomenon of extremely large beam and column sections,which will affect the effective use area of buildings and lack aesthetic feeling.The composite member of concrete-filled steel tubular(CFST)has received extensive attention because of its high structural bearing capacity and good seismic and fire resistance.The slip phenomenon between them will affect the bearing capacity of the components.Therefore,researchers set stiffeners to improve its mechanical properties.Therefore,further research on the axial compressive properties of ribbed CFST is of great significance to engineering practice.
