On lap splice length of lap-spliced crossties for reinforced concrete columns under cyclic loading
Advances in Structural Engineering, 2020A lap-spliced crosstie comprises two J-shaped rebars, each with a 180° hook at one end and straight at the other end. Six large reinforced concrete columns subjected to lateral cyclic loading were tested. The results indicated the following: (1) the confining effect of horizontally lap-spliced crossties is similar to that of vertically lap-spliced ...

Lap Splice Length and Fatigue Performance of Fiber-Reinforced Polymer Laminates [PDF]
ACI Materials Journal, 2002 When carbon fiber reinforced polymer (CFRP) laminates are used in strengthening long structural members, lap splicing is usually adopted for the transition of forces. Determination of the effective lap splice length and its fatigue performance is of importance.

Applied Mechanics and Materials, 2012
In this study, 2D finite-element study was performed to evaluate the lap spliced length of GFRP rebar of concrete beam designed according to requirements of the current design codes. The analysis models using the general-purpose computer program ABAQUS 6.10-1(2010) are based on the test results of previous researcher.

Strength of compression lap-spliced GFRP bars in concrete columns with different splice lengths
Construction and Building Materials, 2018Abstract Recent years have seen valuable research work on using glass-fiber-reinforced-polymer (GFRP) bars in reinforced-concrete (RC) members under compression. Nonetheless, lap splicing of GFRP bars under compression has not yet been explored with due consideration of its components.

Tension Lap Splice Length in High-Strength Concrete Flexural Members
Journal of the Korea Concrete Institute, 2009This paper presents the test results of total 24 beam-end specimens to investigate the effect of high-strength con- crete and cover thickness on the development resistance capacity in tensile lap splice length regions. Based on bond characteristics that an increase in concrete strength results in higher bond stress and shortening of the transfer length,

Journal of the Korea Concrete Institute, 2010
Although the compression splice needs not be longer than the tension slice due to existence of end bearing, current design codes impose a longer compression lap splice than a tension lap splice in high strength concrete. Hence, new criteria for the compression lap splice including the effects of concrete strength need to be sought for economical design

Compression Lap Splice Length in Concrete of Compressive Strength from 40 to 70 MPa
Journal of the Korea Concrete Institute, 2009A compression lap splice becomes an important issue due to development of ultra-high strength concrete. Current design codes regarding compression lap splice do not utilize merits of the improved strength of ultra-high strength concrete. Espe- cially, a compression lap splice can be calculated longer than a tension lap splice according to the codes ...
