Lap splices, then, can be considered structurally less reliable and design-constrictive, with many ‘hidden’ costs. As a result, usage of mechanical splices previously considered cost-prohibitive is on the rise.

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.

WebFor contact lap splices, minimum clear spacing between the contact lap splice and adjacent splices or bars shall be in accordance with the requirements for individual bars in 25.2.1. 25.5.1.3 For noncontact splices in flexural members, the transverse center-to-center spacing of spliced bars shall not exceed the lesser of one-fifth the required lap splice length and 6 in. shared reading in early yearsWebSplices of reinforcing bars are unavoidable.
