Behavior of masonry strengthened infilled reinforced concrete frames under in-plane load

HBRC Journal, 2015
Experimental tests have been carried out to study the behavior of different single story frames infilled with brick masonry under the in-plane lateral load influence. Three phases of frames were tested.

CFRP Materials for Restoration of the Bearing Capacity of RC Beams With Damaged Rebar

Journal of Engineering, Volume 2024, Issue 1, 2024.
Corrosion of the rebar in reinforced concrete (RC) structures is a critical concern, compromising their reliability and long‐term operation. Carbon fibre–reinforced polymer (CFRP) tapes are widely used for strengthening RC structures due to their superior properties such as light weight, high strength and ease of application.

Self-healing of concrete cracks by the release of embedded water repellent agents and corrosion inhibitors to reduce the risk for reinforcement corrosion [PDF]

, 2017
From the worldwide steel production, approximately 50 per cent is required to replace corroded steel [1]. In the case of reinforced concrete structures, corrosion of the reinforcement steel causes crack formation and spalling which leads to ...

A Novel Structural Assessment Technique to Prevent Damaged FRP-Wrapped Concrete Bridge Piers from Collapse [PDF]

, 2009
Repairing deteriorated concrete bridge piers using externally wrapped fiber reinforced polymer (FRP) composites have been proven as an effective approach. This technique has also been applied to low-rise building structures.

A Key Contribution for Concrete Durability: Harnessing Force‐Magnetic Coupling for Stress State Detection in Reinforced Concrete Beams

Structural Control and Health Monitoring, Volume 2024, Issue 1, 2024.
Over the past 20 years, more than 200 major bridge‐collapsed accidents have occurred during their service life. The durability of reinforced concrete (RC) beams is a serious threat to the safety performance of the structures. To accurately grasp the service performance of RC beams, a four‐point bending loading experiment was conducted on RC rectangular
