Experimental and numerical analysis of bending–buckling mixed failure of brickwork walls

The eccentric in-plane loading of masonry walls involves complex bending performance that includes second-order effects. In this work, a bidimensional (2D) simplified micro-model for the analysis of this type of failure is developed. An experimental investigation based on 20 tests of full-scale unreinforced masonry walls is performed. The tests are characterised by slenderness and load eccentricity. The analytical methods of Eurocode-6 and ACI-530 are compared with experimental data from the present investigation, other experimental results available in the literature and simulation results from the numerical model.

► Experimental study of the second order bending failure mode of full-scale unreinforced brickwork walls.
► Experimental analysis of the effect of different slenderness and eccentricities.
► Test setup for testing hinged full-scale masonry walls in laboratory.
► Numerical simulation of walls under eccentric compressive loads taking into account geometric and material non linearity.
► Comparison from different experimental programs, analytic standards solutions and the proposed numerical simulation.
