Study on the Response of Strengthening Strategies for Masonry-infilled Open Ground Storey Framed Building
Abstract: The strengthening of reinforced concrete (RC) frame buildings with masonry infill wall and with open ground storey is a very timely and significant topic because of the poor performance against seismic action. The absence of infill walls in the ground storey makes the ground storey less stiff and weaker than the all upper storys which results in a poor performance against lateral loads. Soft storey mechanism prevails in these cases …
