Techniques for Reinforcing the External Fixator

1985
We have discussed the standard operative technique for the external fixation of a tibial fracture under normal circumstances. Here we shall describe some special techniques that have proved useful for augmenting the stiffness of the frame.

The Role of External Variables in Self-Reinforcement

Behavior Modification, 1977
The present paper reviews self-reinforcement research in behavior modification. This research suggests that a wide range of responses can be altered, including classroom deportment, academic performance, and studying as well as eating behaviors, smoking, nail-biting, and others.

Self-reinforcement: A continuum of external cues.

Journal of Educational Psychology, 1980
This experiment was designed to investigate the role of external influences in children's self-regulatory behavior under stringent-demand and lenient-demand conditions. The abilities of a stringent-demand condition (in the form of stringent instructional sets and criterion setting) and a lenient-demand condition (in which lenient instructions were ...

External Reinforcement of Concrete Beams Using Fiber Reinforced Plastics

ACI Structural Journal, 1991
A series of 16 under-reinforced beams was tested to study the effectiveness of external strengthening using fiber reinforced plastic (FRP) plates. Plates of glass, carbon and aramid fibers were bonded to the tension side of the beams using a 2-part epoxy.

ANALYSIS OF REINFORCEMENT OF RACKS OF CONICAL REINFORCED CONCRETE BY EXTERNAL REINFORCEMENT WITH POLYMER COMPOSITE MATERIALS

PROBLEMS OF APPLIED MECHANICS, 2020
A method of reinforcing conical reinforced concrete struts by external reinforcement with composite materials is considered. The calculation of reinforced concrete struts according to the limiting states of the first group, reinforced with composite materials in accordance with the requirements of SP 63.13330.2012 and SP 164.1325800.2014.

External Plate Reinforcement for Concrete Beams

Journal of Structural Engineering, 1998
Strengthening concrete beams for shear forces by means of attaching steel plates to the external surfaces could provide a practical solution to the program of upgrading concrete bridges for carrying heavier loads. The experimental study carried out on three beams with 2, 4, and 6 mm plates attached by bolting to the vertical sides (web) of the beams ...

Textile reinforced cement as an externally bonded reinforcement for concrete beams

2011
Standard cementitious materials are characterized by a brittle behaviour and a low tensile strength. The most common way to solve these problems is the use of steel reinforcement, but due to the need of a cover for corrosion protection, this results in heavy and massive constructions.

Self-reinforcement: An assessment of external influences

Journal of Behavioral Assessment, 1979
Two experiments were carried out in which low- and high-demand characteristics of self-reward were assessed in a multiple-baseline design across subjects. In the first experiment, arithmetic performance of four children was systematically assessed under no-reinforcement, self-reward/low-demand and self-reward/high-demand phases.

Strengthening of a reinforced concrete bridge with externally bonded steel reinforced polymer (SRP)

Composites Part B: Engineering, 2007
This paper introduces steel reinforced polymer (SRP) as a way to strengthen civil structures. This technique consists of cords formed by interwoven high-strength steel wires embedded within a polymeric resin. A comprehensive study addressing analysis, design, installation, load rating and monitoring of a bridge strengthened with this technology is ...

Ductility of Reinforced Concrete Members Externally Wrapped with Fiber-Reinforced Polymer Sheets

Journal of Composites for Construction, 2007
The effectiveness of external wrapping with fiber-reinforced polymer for enhancing the curvature ductility of lightly reinforced concrete members is investigated. Referring to members with circular transverse cross sections, the performances in terms of both strength and ductility capacities are analyzed, and the predictive reliability of two different
