Flexural Strengthening of Reinforced Concrete Beams with Substandard Tension Lap Splices Using a Novel Pre-stressing Technique

open access: yesInternational Journal of Concrete Structures and Materials
Sudden failure of reinforced concrete (RC) beams with substandard tension lap splices due to low resistance to flexure is a critical issue that needs to be addressed. Accordingly, a novel pre-stressing technique is presented in this paper, which offers a

Optimizing Rebar Consumption and Cutting Waste in Column Reinforcement: Integrated Mechanical Couplers and a Special-Length-Priority Minimization Algorithm

open access: yesBuildings
The construction of reinforced concrete (RC) structures inevitably consumes an excessive number of rebars, leading to significant cutting waste and carbon emissions.

Combined mechanical couplers and special-length-priority algorithm for reducing rebar consumption and cutting waste of beam reinforcement

open access: yesResults in Engineering
The surging demand for reinforced concrete buildings has led to excessive consumption of rebars, resulting in substantial rebar-cutting waste and greenhouse gas emissions. Various approaches have been explored to mitigate this issue, including lap-splice

Splice tests of plain steel bars in concrete [PDF]

open access: yes, 2011
Fifteen splice specimens reinforced with plain steel bars, including three specimens instrumented with both steel and concrete strain gauges, were tested under monotonically applied four-point loading to develop a database of reliable bond test results ...

Performance of connection joints of beam-column structure using Ultra-high-performance concrete under full-scale tests

open access: yesDevelopments in the Built Environment
This study examines the application of Ultra-High Performance Concrete (UHPC) in precast beam-column joints to improve structural performance. The studied joints included both adequately and inadequately reinforced conditions (strong and weak joints ...

High cycle (fatigue) resistance of reinforced concrete beams with lap splices [PDF]

open access: yes, 1993
The development of current design standards for reinforced concrete beams containing lap splices has been mainly aimed at preventing failures due to static (monotonic) loading, or low cycle, high intensity (seismic) loading.

Using Near-Surface-Mounted Small-Diameter Steel Wires to Improve Construction Efficiency in Strengthening Substandard Lapped Spliced Reinforced Concrete Beams

open access: yesBuildings
Strengthening lapped spliced reinforced concrete (RC) beams using tiny-diameter steel wires as near-surface-mounted (NSM) rods has not been carried out previously.

Performance of Reinforced Concrete Column Lap Splices [PDF]

open access: yes, 2010
Cantilevered reinforced concrete columns with a lap splice of the longitudinal reinforcement near the base can induce high moment demands on the splice region when lateral loads are present on the structure.
