- Abstract
- Equations for a hand computation of moment-axial forced domain of R.C. members externally strengthened with steel angles and strips are developed here. The analytical derivation was made assuming equivalent stress-block parameters for internal force considering the confinement effect induced in concrete core by external cages. Simple analytical equations are proposed on the basis of constitutive laws of confined concrete and steel angles recently developed by the author. The proposed model gives results in a good agreement with available experimental data and it allows one a hand control of the influence of main parameters governing the problems (angles and strips geometry and mechanical properties of constituent material) on the behaviour of R.C. columns externally strengthened with steel cages.
