Cold joints in reinforced concrete (RC) beams can significantly impact shear behavior, influencing stress distribution and failure patterns. This study examines how delay times, compressive strength, and
This study examines the impact of cold joints on the strength and stiffness of reinforced concrete beam-column connections through experimental testing on two specimens, one monolithically poured and
Cold joints, formed due to interruptions in the concrete placement process, significantly impact the mechanical behavior of concrete structures. This study comprehensively examines the
It was found that cold joints generally reduced the flexural strength of beams, with the extent of the reduction varying depending on the joint''s location, orientation, and the time between
Abstract The cold bending process is often applied to the welded structures during manufacturing, but how it influences the properties of the welded joint is still poorly understood.
This study investigates the effects of cold joint location and angle on the mechanical properties of concrete, focusing on compressive and flexural strength, modulus of elasticity, toughness, and
In the present study, the effects of cold joint type on bending behavior of reinforced concrete (RC) beams were investigated. Within this scope, four point bending tests of a total of
Cold joint concrete is a phenomenon that occurs due to the lack of the bonding or intermixing of the two concrete layers with each other. The cold concrete joint is a crack that is found
It was found that strength losses due to drying–wetting and freezing–thawing of specimens with cold joints were higher than those of the specimens without cold joints. Strength losses of
This study would test the compressive and flexural strength due to the effect of cold joint in concrete. The period of the casting between two concrete (cold joint) was 120 minutes and 240 minutes.
A cold joint is the main problem in concrete construction, especially in large quantities such as mass concrete. The capacity of mixing plan and manpower make monolith casting is impossible. The
By analyzing the impact of cold joints in various locations and angles, the study provides valuable insights for construction professionals, including clients, contractors, and on-site workers, to
Abstract This study investigated the efects of cold joints on the strength and some durability properties of concrete. In the first part of the study, fresh concrete was poured into molds filling them half in order
From the experimental study, the amount of loss in the flexural strength capacity of the RC beams due to the presence of cold joint for different age was observed. A deduction chart to
Cold joints affect tunnel service performance by influencing the damage extent and cracking of lining concrete. Reductions in steel bar diameter and bedding coefficients exacerbate the
PDF | This study investigated the effects of cold joints on the strength and some durability properties of concrete.
In addition to the concrete grades, cold joint angle is also a parameter to be investigated. Zero angle was the control angle. Besides, 20, 45, 65 and 90 degrees were studied to understand
The aim of this study is to determine the effect of cold joints formed at different times on the strength of concrete. Additionally, this experimental study presented here investigates the effect
The effect of time and of cold joint on chloride diffusion is an important parameter for quantitative durability design for RC (Reinforced Concrete) structures exposed to various loading
The present study aims at investigating the effects of cold bending on residual stress, microstructure and hardness of Type 316L stainless steel welded joint. In this work, welding residual
Abstract This study introduces a mechanics-based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading.
ufacturing error that causes poor adherence at the concrete interface as a result of concrete being poured at different times. The main purpose of this study is to investigate the bending .
Abstract Cold joints, a prevalent defect in mass concrete casting, pose significant risks to the structural integrity and load-bearing capacity of constructions. Despite their critical implications,
The aim of this study is to determine the effect of different angled cold joints in the shear zone on the behaviour and load carrying capacity of 4 point loaded beams under bending.
