The conventional approach to connecting reinforcement bars has predominantly relied on lap splicing, where two bars overlap for a specified length and are tied together. This method, while widely used, presents several inherent limitations. The required overlap length can be substantial, sometimes reaching up to 40 times the bar diameter, leading to congestion in heavily reinforced sections. The effectiveness of lap splices depends heavily on proper concrete consolidation around the splice region. These limitations become even more pronounced in seismic zones as the demands on structural connections increase significantly. The construction industry has long recognized these constraints, spurring the search…
