Behaviour of reinforced concrete beams strengthened by external unbonded reinforcement

Construction and Building Materials, 1997
Abstract Retro-fitting of external unbonded reinforcement as a mean of strengthening concrete beams deficient in flexural strength has been investigated in a short programme of experimental and analytical research to evaluate the potential of the technique.

Schema Discrimination without External Reinforcement

Perceptual and Motor Skills, 1967
In two discrimination tasks, Ss readily learned to distinguish members of a schema family from non-members. This learning occurred in an insightful manner without external reinforcement.

A new composite for external reinforcement: Steel cord reinforced polymer

Construction and Building Materials, 2008
Abstract Today, mostly steel plates and carbon fibre reinforced polymers (CFRP) are used as external reinforcement. This paper deals with a new material that can be used as external reinforcement: steel cord reinforced polymer (SCRP). It consists of thin high-strength steel fibres embedded in a polymer matrix.

Strengthening RC Beams by External Reinforcement

, 2006
The proposed paper aims to describe a novel strengthening technique for reinforced concrete beams which employs non-prestressed external reinforcing bars anchored at the supports of simply supported beams or slabs. External reinforcement can be easily retro-fitted to existing reinforced concrete structures.

External Prosthetic Reinforcement of the Pulmonary Autograft

The Thoracic and Cardiovascular Surgeon, 2018
Background Neo-aortic root dilatation accounts for the majority of reoperations needed after the Ross procedure with implantation of the pulmonary autograft as complete root replacement. This study evaluates early results of external prosthetic reinforcement of the autograft.

Investigation of a flat reinforced concrete slab reinforced with external prestressed reinforcement

Building constructions. Theory and Practice, 2020
When installing monolithic reinforced concrete flat floors, there are often problems associated with excessive deflections and cracks.They can occur both during operation and during construction.The reasons for excessive deflections include: deviations from the manufacturing technology, design errors, and so on.In this case, the structure may become ...

Basalt fiber reinforced polymer grids as an external reinforcement for reinforced concrete structures

Journal of Reinforced Plastics and Composites, 2015
This paper presents series of experimental studies on newly developed basalt fiber reinforced polymer (FRP) grids for the flexural strengthening of reinforced concrete beams. The study includes tensile behavior of the basalt FRP grids with three types of thickness, bonding behavior between the basalt FRP grids and the concrete with epoxy resin, and ...

FRP Reinforcement of Externally Pressurised Torispherical Shells

1989
The aim of the paper is to analyse the effectiveness of FRP reinforcement of steel torispherical shells. The failure modes of unreinforced and reinforced torispheres are studied, taking into account the various geometrical and mechanical properties of the shells and reinforced layers.
