Comparison of Different Strengthening Techniques of Damaged and Weak Reinforced‒Concrete Frames
As part of a broader research project, attention of this study has been focused on the existing, damaged “strong frame“ RC buildings and “weak frame“ RC buildings, strengthened with clay brick masonry infill walls (“framed‒ wall”). We experimentally investigated different masonry wall application techniques within the frame that upgrade the seismic capacity of these structures. Seven one‒bay, one‒storey RC frames were built in a scale 1:2.5 and 1:2, “strong“ and “weak” frames respectively. They were tested under constant vertical and reversed cyclic lateral loading up to the drift of 1.5%. The experimental results are presented in the form of observed failure mechanism, hysteresis loops and cyclic envelope curves. The tests showed that RC frames strengthened with masonry infill wall had the improved lateral load and deformation capacity as well as energy dissipation. The system behaved as composite “framed‒masonry” structure which damage could be controlled. Cost‒ effectiveness and simplicity of the technique by the implementation of the masonry infill wall seems to be much more favourable than just the repair of the existing RC bare structure.
