Abstract
Masonry infill panels in frame structures have been long known to affect strength, stiffness and ductility of the inflled frame structures. In seismic areas, ignoring the composite action is not always on the safe side, since the interaction between the panel and the frame under lateral loads dramatically changes the dynamic characteristics of the composite structure and hence its response to seismic loads. It has been generally recognized that infill walls enhance the response of frame buildings in low to moderate seismic regions, yet they exhibit poor seismic performance under high seismic demand because of the degradation of stiffness, strength and energy dissipation capacity observed under cyclic loading. Their degradation results from the progressive damage of the masonry wall and the deterioration of the panel-frame interfaces. This paper presents a retrofitting methodology of concrete masonry infill panels using fiber reinforced polymer (FRP) laminates. The method is expected to enhance the system behaviour under strong earthquake loads as has been shown by test results. This method also prevents the undesirable failure modes and facilitates modeling by eliminating the anisotropic nature of masonry panels and clearly defining the behaviour of the retrofitted system.
