THE STUDY AND APPLICATION Of CONCRETE BOUNDING SURFACE CONSTITUTIVE RELATIONSHIPS TO THE NONLINEAR FINITE ELEMENT ANALYSIS OfCONCRETE FILLED STEEL TUBULAR STRUCTURES

  • Based on theoretical analyses and the results of tests, the paper studies concrete bounding surface constitutive relationships. The behavior of the material under multi-axial loading is taken into account completely and accurately in the relationships. It is shown that the relationships are simple and effective in nonlinear finite element analysis.
