Description: A two-dimensional non-linear finite element program, named Confine4.1, was developed to analyze the confining effects in columns and beams. The constitutive material model was selected and slightly modified from other models available in the literature. The program was verified against 18 columns tested under concentric compression and two columns tested under eccentric compression. The program was able to accurately predict the load-strain response and the moment curvature response of the columns, including the post-peak response. The use of a triaxial failure criterion allows the prediction of cover spalling to be made. The program was able to distinguish the effects of varying concrete strengths, transverse yield strength and the amount of transverse reinforcement. Confine4.1 is a research tool and further work is needed before can be used in day-to-day engineering.
