摘　　要：在工程中应用钢管混凝土组合结构能有效发挥出各类型材料的优点,并且能避免单一材料缺点带来的不良影响。随着工程结构面向高层、大跨度及重载等方向发展,对钢管混凝土结构性能的要求不断提高,希望能够在保持结构性能不变的基础上减少钢的使用量,并且希望钢管混凝土结构本身可以更加轻便、截面面积更小。在这样的情况下,CFRP-钢管混凝土结构在工程中的应用越来越广泛,工程质量得到显著提升。基于此,本文对CFRP-钢管混凝土柱钢梁节点的发展概况进行简要分析。The application of CFST composite structure in engineering can effectively play the advantages of various types of materials,and can avoid the adverse effects of single material defects.With the development of engineering structure in the direction of high-rise,large span and heavy load,the requirements for the performance of concretefilled steel tube structure are constantly improved.It is hoped that the steel consumption can be reduced on the basis of keeping the structural performance unchanged,and the concrete-filled steel tube structure itself can be more porta⁃ble and have a smaller cross-section area.In this case,cfrp-cfst structure is widely used in engineering,and the engi⁃neering quality has been significantly improved.Based on this,this paper briefly analyzed the development of cfrpcfst column steel beam joints.
