CFRP钢管混凝土轴压短柱混凝土本构关系
Constitutive relation of concrete of concrete-filled CFRP-steel tubular short columns with axial compression
摘要
Abstract
The constitutive relation of core concrete for concrete-filled CFRP-steel tubular columns is put forward based on modified constitutive relation of core concrete of concrete-filled steel tube,and a commercial ANSYS FE software is employed for the simulation of the relation of stress and strain of concrete-filled CFRP-steel tubular short columns with axial compression.An experimental investigation was performed on 12 specimens,including 8 concrete-filled CFRP-steel tubes and 4 concrete-filled steel tubes.Numerical analysis results curves are consistent with the test data,which proves that the provided constitutive relation of concrete is fit for the concrete-filled CFRP-steel tubular short columns with axial compression.关键词
