Study on Axial Compressive Performance of Prefabricated FRP-Steel-Concrete Composite Column
摘要
This paper adopts the method by combining the experimental research and theoretical analysis to study the axial compressive performance of prefabricated composite columns. The research is mainly focus on two type of composite column, called ISFTC and IFSTC, composed by FRP, steel tube and concrete. Finite element analysis was carried out to study the influence of inner and outer tubular diameter on the constraining effect. Based on the unified strength theory of double shear and experimental data collected from former literature, the bearing capacity of composite column and the sectional optimization design method was proposed.
