Abstract

Ultra high performance concrete (UHPC) is a new type of cement-based composite material with superior mechanical and durability properties, which can reduce the self weight of the structure and prolong its service life. Based on this, a finite element model of 10 composite columns was established to analyze the axial compressive stress process, and to explore the effects of concrete strength, UHPC thickness, and hollow ratio on the mechanical properties of composite columns. The results indicate that UHPC has the highest proportion of load sharing under the ultimate bearing capacity state, while steel pipes have the lowest proportion of load sharing. The ultimate bearing capacity and initial stiffness of composite columns can be improved by increasing the concrete strength, UHPC thickness and decreasing the hollow ratio, and the deformation coefficient of composite columns can be reduced by increasing the hollow ratio.
