- W2591837671 abstract "Finite element models w ere proposed using the program ABAQUS to analyze the bearing capacity of recycled concrete filled circular steel tubular stub columns under compressive loading,w hich verified the modified mathematical expression proposed by authors for recycled concrete constitutive relationship. Specifically,the Coulomb friction model w as applied to describe the contact interface of the steel tube and the core concrete. Three-dimensional octahedral solid elements w ith 8 nodes linear reduced integration( C3D8R) w ere used for the core concrete and the top plate and linear elements w ith 4 nodes reduced integration( S4R) for the steel tube. One end of the column w as fixed,w hile the other w as subjected to a displacement load. Results show that the ob-tained deformation curves by the finite element analysis accord w ith the know n test results w ell. It is also found that the bearing capacity of recycled concrete filled circular steel tubular stub columns reduces w ith increasing of the replacement rate of recycled concrete. It is seen that the proposed modified formula by authors for recycled concrete constitutive relationship can meet requirements of precise analysis of stub columns under compressive loading based on ABAQUS." @default.
