WebLap splices allow the use of shorter vertical bars by transferring stresses from one reinforcing bar to another through the development of the splice. However, lap splices increase the total volume of reinforcement in a wall and can impact the cost of the project. Masonry contractors have estimated that 80% of laps occur at vertical bars. WebMechanical bar splices are an engineering method used to connect reinforcing bars, which are widely used in bridge construction, foundation projects, high-rise buildings and other fields. Compared with traditional connection methods such as welding and lap splicing, mechanical bar splices have better load-bearing capacity,

WebReinforcing bars can also be spliced using end-bearing splices, but only in members containing closed ties, closed stirrups or spirals for bars subject to compression only. End-bearing splices rely on the transmission of compressive stress by bearing of square-cut ends held in concentric contact by a suitable device. WebJun 22, 2024 · Lap Splicing.
