Macro and micro polypropylene fiber effect on reinforced concrete beams with insufficient lap splice length

Case Studies in Construction Materials, 2022
For longer spans of reinforced concrete elements, design codes dictate the use of sufficient lap splice length. Insufficient lap splice length decreases the flexural strength and ductility of reinforced concrete (RC) beams, while fiber addition improves ...

Feasibility of Reduced Lap-Spliced Length in Polyethylene Fiber-Reinforced Strain-Hardening Cementitious Composite [PDF]

Advances in Materials Science and Engineering, 2018
This research investigates the interfacial behavior between polyethylene (PE) fiber-reinforced strain-hardening cement composite (PE-SHCC) and reinforcing bars that are spliced in the tension region to determine feasibility of reduced lap-spliced length ...

Simplified Design Equation of Lap Splice Length in Compression [PDF]

International Journal of Concrete Structures and Materials, 2010
With the emergence of ultra-high strength of concrete, the compression lap splice has become an important area of interest. According to ACI 318-08, a compression splice can be longer than a tension splice when high-strength concrete is used. By reevaluating the test results of compression splices and performing regression analysis, a simplified design

Effect of GFRP Stirrup Confinement on the Bond Strength of GFRP-RC Beams [PDF]

International Journal of Concrete Structures and Materials
The current provisions for development length in the ACI 440.11 code disregard the confinement effect provided by stirrups on the bond strength of longitudinal bars and require splice lengths that pose implementation challenges.

An experimental investigation on contact compression lap splice in circular columns

HBRC Journal, 2016
Due to the rapid development in design of multistory buildings and, because of the variation in stories height with the fixed length of the steel reinforcing bars, steel is usually wasted particularly in columns. Hence, compression lap splice may be used

Behavior and Splice Length of Deformed Bars Lapping in Spirally Confined Grout-Filled Corrugated Duct [PDF]

Advances in Materials Science and Engineering, 2019
This paper discusses the behavior of grouted noncontact lap splices under monotonic tension load. Deformed bars lapped through a grout-filled corrugated duct, and a spiral reinforcement was preembedded in the connection to improve tensile strength of the

Optimization of lap splice positions for near-zero rebar cutting waste in diaphragm walls using special-length-priority algorithms

Journal of Asian Architecture and Building Engineering
Construction processes often result in rebar waste when cutting stock length rebar to required length, incurring significant costs and contributing to CO2 emissions.

Seismic Behavior of Circular Sectional RC Bridge Columns with Various Lap-splice Lengths - An Experimental Study - [PDF]

Journal of the Earthquake Engineering Society of Korea, 2012
It is known that seismic performance of existing bridges having insufficient lateral confinements and lap-splices of longitudinal reinforcements at the base of column decreases dramatically. In this study, small-scaled model tests have been performed to confirm the seismic behaviors of RC bridge piers with various lap-splice lengths.

Strengthening of RC beams with inadequate lap splice length using cast-in-situ and anchored precast ECC ferrocement layers mitigating construction failure risk

Case Studies in Construction Materials
Design standards necessitate the use of a sufficient lap splice length when dealing with longer spans of Reinforced Concrete (RC) members. An inadequate lap splice length results in a reduction of both the flexural strength and ductility of reinforced ...
