Mechanicsābased model for cold joints in reinforced concrete
Abstract This study introduces a mechanics-based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading.
This study aims to investigate the mechanical properties of cold joints, which typically exhibit reduced strength compared to surrounding materials, thereby raising concerns about their failure under ...

Abstract This study introduces a mechanics-based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading.
To resolve the issue of cold joints forming in concrete during the construction process, this study has developed a control system with visual prevention capabilities.
Using current cold joint simulations, the dispersive velocity profile and the amplitude of the displacement waveform of the R-wave confidently enable the identification of cold joints with a porosity ratio
Drawing upon existing literature, including numerical simulations and experimental testing, this study presents a robust simplified numerical simulation modeling framework for
Thus, this study investigates types of cohesive elements used for simulating cold joint defects in concrete to aid the analysis of the crack propagation law and the structural failure modes
The study aims to measure the reduction in compressive and flexural strength of concrete specimens containing cold joints, evaluate the effect of cold joint orientation (vertical, horizontal, or
The study utilizes a database of 217 cold joints, categorized by surface type (smooth or roughened), and employs a range of input parameters, including concrete strength, reinforcement
This study would to test the compressive and flexural strength due to the effect of cold joint in the concrete.
The report will consider case studies where cold concreting joints were found, both horizontal and inclined. Examples of calculation and reinforcement of structures with identified cold
