Practical Seismic Strengthening of R/C Beam-Column Joints Without Lateral Reinforcements in Developing Countries

Abstract

Several destructive earthquakes in developing countries in recent years have revealed that a large number of reinforced concrete (R/C) buildings contained no lateral reinforcements in beam-column joints. Severe damage was caused to such beam-column joints due to poor structural capacities, and resulted in complete/story collapse of buildings and loss of human lives. Considering the economic and technical conditions in developing countries, this paper proposes a practical seismic strengthening method fo…
