Abstract

Abstract

Based on the axial compression test of 9 reactive powder concrete (RPC) short columns confined by square steel tubes (the concrete mixed with steel fibers and built-in spiral stirrups), the effects of steel fiber content and spiral stirrup spacing on the failure mode, bearing capacity and ductility of columns were studied. The test results showed that the deformation capacity of the specimen could be greatly improved by adding steel fibers and embedding spiral stirrups, and the increase range of ultimate bearing capacity could be up to 10%~25%. Based on the experiment, the ABAQUS finite element analysis model was established to further analyze the influence of length-thickness ratio and stirrup spacing on the bearing capacity and ductility of columns,the results of theoretical analysis could provide theoretical support for engineering practice.
