Abstract: The lateral and axial strain relationship plays an important part in predicting the confinement of confined columns. Measuring lateral strains in compressive experiments proves to be difficult which mean few reliable results are available. A lateral strain versus axial strain model is proposed based on the supposition that the concrete behaves linear elastically in the early stages of loading, nonlinear hardening up to the peak stress after which the inelastic lateral strain vary linearly with the inelastic axial strain. The lateral to axial inelastic strain ratio is shown to be a function of the lateral confinement level and related to the failure mechanism. Moreover, size effect is also discussed from the lateral strain versus axial strain perspective.
