Seismic Strengthening of Masonry Infilled Reinforced Concrete Frames
Reinforced concrete frame buildings with masonry infill walls are being widely used in seismic prone regions in Southern Europe. For seismic design and evaluation of existing buildings, the contribution of infill walls is usually neglected although it can be and usually is beneficial. Its contribution is of special importance for seismic strengthening of r/c frame buildings, where it can be of special importance. Strengthening methods are not sufficiently investigated, especially experimentally, and the investigation of these is necessary. Within the scope of our research, we have planned to investigate possible strengthening methods, of strong and weak frames, by application of the masonry infill. Up to now, following strengthening methods of the strong r/c frame, were investigated: a) Masonry infill anchored to the surrounding r/c frame, b) Reinforced masonry infill anchored to the surrounding r/c frame and c) Masonry infill wall with additional confining element. Reinforced concrete frame was designed according to the EC8 and for masonry infill we used hollow and solid clay masonry units. One story- one bay specimens, built in a scale 1:2.5, were tested under constant vertical and cyclic in-plane lateral loads. Tests were performed at the Laboratory for experimental mechanics at the Faculty of Civil Engineering in Osijek, Croatia. The test details and experimental results will be presented at the Bauhaus Summer School in Weimar 2012. Specimen details and applied strengthening methods are presented. The results of strengthened specimens, are compared to the previous experiments when the r/c frame was without infill and with infill with no connection to the frames.
