The lap splice length of the reinforcement in a fiber-reinforced strain-hardening cement composite (SHCC), which has strain-hardening behavior and a capacity to control macrocracks in direct tension, can be lesser (shorter) than that of reinforcement used in conventional concrete.
The variables include the replacement levels of an expansive admixture (0% and 10%), the compressive strength of the SHCC mixtures (40 MPa and 80 MPa), and the length of the lap splice in the tension region (40% and 60% of the splice length recommended by ACI 318).
Fatigue analysis of an AL 2024-T3 Alclad cracked lap splice

Therefore, a minimum splice length of 40 times the rebar diameter for GFRP and 25 to 30 times for steel is required, with at least three secure ties for each lap splice
. Regular steel tie wires were used for the steel rebars and plastic zip ties for the GFRP.
Another type of splice used in many converting operations is the lap splice
, in which the trailing edge of the expiring web overlaps the leading edge of the new web.
The most common method is the lap splice
, where belt ends are cut on a bias and overlapped for joining.
Poor seismic detailing of the column ends showed the existence of a lap splice
of the longitudinal reinforcement within the potential plastic hinge zone with a length of 40 in.
Every steel installer knows how to create a lap splice
when installing rebar in a new pool.
The manufacturer should also provide certification that the U-channel lap splice
system furnished will develop the full shear and bending yield strength of the sign post section being spliced.
It can also be equipped to provide heat-seal lap splices
for thermo-bondable materials.
This was particularly important due to the lap splices
used between deck panels and between stages on the truss spans.
The aluminum skin panels of an airplane overlap in long seams called lap splices
, which are held together by adhesives and rivets.
