Several empirical formulae were proposed for the practical estimation of the load bearing capacity of reinforced and unreinforced masonry walls under buckling. Critics were reported on the methods of Eurocode 6. The solutions provided in the current version of Eurocode 6 show inconsistency at a specific range of masonry materials. The authors have recently proposed a solution for unreinforced masonry walls to replace the current formula in EC6. Some other works proposed solutions for reinforced masonry based on the nominal curvature. However, the current work shows that one unified solution can be proposed for both unreinforced and reinforced masonry walls and no need to handle each case separately. The proposed solution is based on representing the relationship between the capacity reduction factor Φ and the slenderness ratio ߣ by using two curves. One is a parabola for the material failure region and the other one is a hyperbola for the stability failure region. The proposed solution for unreinforced masonry have been checked against experimental data and the calibration parameter has been determined. The same concept has been used to generalize the proposed solution for reinforced masonry walls as well.
