Regression prediction model for shear strength of cold joint in
Multiple linear regression (MLR), random forest regression (RFR), and support vector machine regression (SVR) prediction models for cold joint shear strength were established based on
Mechanics-based model for cold joints in reinforced concrete members
Abstract This study introduces a mechanics-based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading.
An experimental and numerical study on the effects of cold joint
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

Simplified Numerical Simulation Modeling of a Reinforced Concrete
Drawing upon existing literature, including numerical simulations and experimental testing, this study presents a robust simplified numerical simulation modeling framework for
Concrete Beam
Ask the price for a cold joint bulkhead between the slab and the beam in order to place the beam monolithically. A second placement can be used to make the slab. Keep in mind that to
