Monotonic and Cyclic Seismic Analyses of Old-Type RC Columns with Short Lap Splices
Construction MaterialsReinforced concrete (RC) columns with short lap splices built in the early 1970s or before are known to have deficient seismic strength and ductility. These short lap splices are poorly confined and located right above the foundation level, where it is ...

Tension Lap Splices in Recycled-Aggregate Concrete Strengthened with Steel–Polyolefin Fibers
FibersThe bond strength of tension lap splices in recycled-coarse-aggregate-reinforced concrete strengthened with hybrid (steel–polyolefin) fibers was experimentally investigated. This study was conducted with the help of twelve lap-spliced beam specimens. The

An investigation into the tension lap splices
Engineering Future Sustainability, 2020 The purpose of this study is to investigate the effect of lap joint length on structural performance under ultimate load using both nonlinear numerical analysis and laboratory experiments. Three-dimensional (3D) finite element models were employed for the numerical simulations, which were carried out using LUSAS software.

Reducing Rebar Cutting Waste and Rebar Usage of Beams: A Two-Stage Optimization Algorithm
Buildings, 2023 While various approaches have been developed to minimize rebar cutting waste, such as optimizing cutting patterns and the lap splice position, reducing rebar usage by minimizing the number of splices remains uninvestigated. In response to these issues, a

Performance of Tension Lap Splice in Lightweight Concrete
International Journal of Engineering and Advanced Technology, 2020 The use of Light-Weight Concrete (LWC) in modern construction has resulted in efficient designs and considerable cost savings by reducing structural own weight and supporting footings sections. The purpose of this paper is to investigate the Lap-Splice behavior between LWC and steel reinforcement (RFT).
