Results of an experimental program to investigate the behavior of multilayer infill panels are presented here. For the purpose five single or multilayer infilled frames are tested under cyclic loading. The most important advantage of multilayer infilled frames is the possibility of adjusting their stiffness and strength, and it is one step forward to produce engineered infill panels. The strength and stiffness of such panels can be adjusted by changing the material properties and thickness of the constitutive layers. Strengths of multilayer specimens are compared with single layer infill panels. It was observed in experimental tests of multilayer infilled frames, composed of concrete and masonry layers, that the decrease in the entire thickness of brick layers or increase in total thickness of concrete layers will reduce the displacement of the ultimate strength. Stiffness, strength and damping of the specimens are also presented and compared.
