Seismic performance of steel fiber reinforced concrete

Enhancing the Performance of Knee Beam-Column Joint Using

The knee beam-column joint is a critical location in a Reinforced Concrete (RC) structure particularly when subjected to earthquake vibrations. The current structural design codes dictate the use of high amounts of steel reinforcements in the frame joint to manage large strain demands in seismic-prone regions. However, these codes could result in the congestion of steel reinforcements in the
