Comparison of code provisions on lap splices

Structural Engineering and Mechanics, 2007
The code provisions on lap splices are critically assessed in the light of 203 beams without transverse reinforcement and 278 beams with transverse reinforcement. For comparison, the provisions given in the ACI 318, Eurocode 2, and TS 500 Codes are considered.

Earthquake Resistant Tensile Lap Splices

Journal of Structural Engineering, 1983
A review of current code requirements on lap splices and their limitations in seismic design is presented. A simple analytical model of an embedded bar is examined and correlated with available experimental data. The force transfer mechanisms of lap splices and the effects of properly placed transverse reinforcement to avoid brittle failure are studied.

Lap Splices in Reinforced Concrete under Impact

Journal of the Structural Division, 1981
The performance of lap splices subjected to impact loading was studied and compared with that of splices under static loading. Nineteen specimens were tested under impact loading, with failure produced in either one impact, in the three to five impacts of incrementally increasing magnitude, or under either unidirectional or reversed cycling of the ...

Behavior of Multiple Lap Splices in Wide Sections

ACI Journal Proceedings, 1979
In most reinforced concrete catilever retaining walls, construction procedures require some type of splicing of the reinforcing steel. Economics often dictate the use of a lap splice. Since a retaining wall has no redundancy, understanding of splice behavior becomes critical to the design of the structure.

Experimental study of lap splice bolted connection

SPIE Proceedings, 2017
The bolted connection is prone to slip under external load in the lattice transmission tower, which will affect the internal forces and deformation of tower. In order to better simulate the effect of bolt connection slippage on transmission tower, the load deformation relationship should be established.

Behavior of Lap-Spliced Plain Steel Bars

ACI Structural Journal, 2012
Fifteen lap splice specimens reinforced with plain steel bars were tested under four-point loading to investigate bond resistance as a function of development length and bar diameter. Three of these specimens were instrumented with both steel and concrete strain gages to examine bond loss within the lap splice length.

Retrofitting of Rectangular Columns with Deficient Lap Splices

Journal of Composites for Construction, 2010
The cyclic behavior of eight 0.4-scale reinforced concrete column specimens is investigated. The columns incorporated deficient design details to simulate bridge columns built in Washington State prior to 1971. Two columns were tested as reference specimens, five were tested after retrofitting using carbon fiber-reinforced polymer CFRP, and one was ...

Design of Lap-Spliced Bars: Is Simplification Possible?

ACI Structural Journal, 2006
While the estimation accuracy of the strength of lap splices has been improving, the complexity of design for reinforcement development has progressively increased. This research study investigates the development of a simple and reliable design expression.

Lap Splices in Flexurally Loaded Masonry Walls

The Masonry Society Journal, 1995
Ten partially grounded reinforced concrete masonry wall specimens were tested to examine lap splice behavior. Specifically of interest were the effects of variations in the compressive strength of the masonry assemblage upon the performance of lap splices and overall specimen behavior.

Strength of Lapped Splices in Reinforced Concrete Columns

ACI Journal Proceedings, 1979
Results of 51 tests on full scale columns with main reinforcement lap-spliced are presented. Difficulties in evaluating the strength of these specimens led to the development of an alternative method of calculation based on the stress-strain relationship for the concrete.
