Abstract

Abstract

A steel fiber-reinforced self-compacting reactive powder concrete with greater than 255 mm flowability was proposed. Seven fiber-reinforced self-compacting RPC long columns restricted to GFRP tubes were designed. Their mechanical properties under axial load was studied experimentally, with steel fiber admixture, GFRP tube winding angle, and length-to-fine ratio as design parameters. According to the experiment, the steel fiber could improve the compressive and shear resistance of concrete material but had little influence on the column damage characteristics. The ±80°GFRP tubes significantly improved the ultimate bearing capacity and deformation performance compared with the ±45°GFRP tubes. The larger the slenderness ratio, the smaller the initial stiffness and peak load of curve. Based on the calculation model of fiber-reinforced self-compacting RPC short columns restricted to GFRP tubes, the ultimate bearing capacity calculation equation of fiber-reinforced self-compacting RPC long columns restricted to GFRP tubes was proposed based on the discount factor of the length to slenderness ratio relations. The calculation results were in good agreement with the test results, and the error was more acceptable compared with the past test data.
