Abstract

This paper presents a computer program developed by C++ programming language for the analysis of concrete-filled steel tube columns subjected to static load with the consideration of second-order effects and inelastic behavior. The nonlinear tangent stiffness matrix of the column element is formulated by the Rayleigh-Ritz principle with the assumption of fully interaction between the concrete core and steel tube. The arc-length algorithm is also applied to solve the nonlinear equilibrium equation system. The analysis results of the program are compared to the previous research ones in some numerical examples to prove the reliability of the developed program.
