This report increases the knowledge and understanding of the behavior observed in masonry panels, and provides tools to estimate their ultimate capacities. An analytical model was developed to predict the out-of-plane behavior and strength of masonry panels with and without previous in-plane damage. The analytical model was based on an arching action theory. Analytical model parameters included the masonry compressive strength, the infill slenderness ratio, and the extent of in-plane damage experienced by the panel prior to the out-of-plane testing. Experimental testing of a series of specimens was done to verify predictions by the analytical model. Horizontal forces were applied (a) parallel to the plane of an infill and (b) normal to the plane of an infill. Specimens consisted of full-scale reinforced concrete frames with clay brick or concrete block masonry infills. Test specimens were first loaded statically in the in-plane direction up to an arbitrary relative deflection which produced a shear-cracked infill. Specimens were then loaded monotonically with uniform pressures normal to their plane using an air bag. After loading to failure, specimens were repaired and retested. Based on the analytical model and on the supporting experimental results, this research resulted in the development of a seismic evaluation and rehabilitation procedure for unreinforced masonry infill panels loaded normal to their plane.
