CONCRETE CREEP THEORY MODELS AND THEIR FINITE-ELEMENT IMPLEMENTATION

open access: yesВестник Донского государственного технического университета, 2018
The finite-element method for the plane problem solution of the concrete creep theory with regard to aging is developed. The expressions based on the formulas for creep values proposed by N. K. Arutyunyan and S. V.

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.

Influence of chemical and mineral admixtures on shrinkage and creep of prepacked aggregate concrete [PDF]

open access: yes, 2013
Prepacked aggregate concrete is a special kind of concrete which is produced by first placing the coarse aggregates inside the molds followed by injection of grout from underneath using pump or gravity method. The grout consists of sand, cement and water

Flexural performance of concrete‐filled steel tubular beams with wood chip aggregate

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the flexural performance of concrete‐filled steel tubular (CFST) beams with partial replacement of aggregates by wood chips (0%–25%) through experimental and numerical analysis. This study is novel in that it experimentally and numerically investigates the flexural behavior of CFST beams with partial replacement of ...

Mechanics‐based model for cold joints in reinforced concrete members

open access: yesStructural Concrete, EarlyView.
Abstract This study introduces a mechanics‐based numerical model to characterize the behavior of cold joints in reinforced concrete members subjected to monotonic loading. The model incorporates mechanisms such as interface slip and opening, aggregate interlock, clamping force, and dowel action of the reinforcing bars crossing the interface.

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

open access: yesStructural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.
