钢管钢纤维高强混凝土短柱轴心受压试验研究
Experimental research on steel fiber reinforced high strength concrete filled steel tubular short columns subjected to axial compression load
摘要
Abstract
A total of 7 steel fiber reinforced high strength concrete filled steel tubular（SFRCFST） short column specimens and 3 high strength concrete filled steel tubular（CFST） short column specimens were tested under axial compression load.The influences of the volumetric content of steel fiber,concrete strength and steel ratio on the compression behavior of the concrete filled steel tubular short columns were investigated.The results indicate that,with the increasing of the volumetric content of steel fiber,SFRCFST specimens show an increasing trend in ductility and a slight increase in the load bearing capacity.With the steel ratio increasing,SFRCFST specimens show an increasing trend in the load bearing capacity and ductility.With the concrete strength increasing,SFRCFST specimens have an increasing trend in the load bearing capacity,while a decreasing trend in ductility.The failure mode of SFRCFST specimens is not affected by the volumetric content of steel fiber.Based on the results,a simple formula is proposed to calculate the load bearing capacity of the SFRCFST short columns.关键词
