Repaired Reinforced Concrete Beams with Normal and High Strength Concrete

Diyala Journal of Engineering Sciences, 2013
In resent years several attempts were undertaken to repair damaged reinforced concrete structures. Studies on the effectiveness of repaired and strengthened reinforced concrete elements which fail primarily due to formation of major flexural cracks are ...

Appendix B:Model for Single Crack Extension in Lightly Reinforced Beams [PDF]

, 1999
In this appendix the failure behaviour of lightly reinforced concrete beams is investigated. A numerical model based on the fictitious crack approach according to Hillerborg [1] is established in order to estimate the load-deflection curve for lightly ...

Influence of Reinforcement Load Level on Bearing Capacity of RC Beams Externally Reinforced with СFRP

Железобетонные конструкции, 2023
Most of the experimental investigations devoted to the study of the stress-strain state of bent reinforced concrete elements reinforced with carbon fiber-based polymer-composite materials have examined only unloaded beams or beams without preliminary ...

CRACK RESISTANCE OF REINFORCED CONCRETED AND REINFORCED RUBBER CONCRETE BEAMS

Archives for Technical Sciences, 2020
<p>The issue of the appearance and development of cracks, as well as an increase the cracking moment is of particular importance for bending elements operating under aggressive environmental conditions. In structures without cracks, steel reinforcement operates in fairly favorable conditions.

A Termite‐Inspired Alternative to Cement

Advanced Functional Materials, EarlyView.
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,

Near-surface mounted carbon fibre rod used for combined strengthening and cathodic protection for reinforced concrete structures [PDF]

, 2015
The dual function of a carbon fibre reinforced polymer (CFRP) rod working as the near-surface mounted (NSM) strengthening and impressed current cathodic protection (ICCP) anode for corroded reinforced concrete structures has been proposed and researched.
