Seismic performance of repaired RC columns

Magazine of Concrete Research, 2006
Steel or fibre-reinforced polymer (FRP) composite jackets have been utilised in retrofitting reinforced concrete (RC) bridge columns and have shown to be effective in enhancing seismic performance of the structures. However, to date, only a few researches have been conducted on the behavioural characteristics of the repaired RC columns using steel or ...

Bearing Capacity of Corroded RC Columns

2010 Third International Conference on Information and Computing, 2010
This paper reviews previous studies carried out to investigate the behavior of Corroded RC columns. Current tests used to assess the effects of reinforcement corrosion on the serviceability of RC Columns in the absence of a sustained load were first surmised.

Column–joint assembly in RC columns strengthened by steel caging

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2008
The strengthening of reinforced concrete columns by steel cages is one of various techniques available to increase ultimate column loads. Different researchers have shown the importance of the beam–column joint on the behaviour of columns strengthened by steel cages.

Structural repair/strengthening of RC columns

Construction and Building Materials, 1995
Abstract The susceptibility of the majority of the existing building stock to structural damage largely depends on the quality of design, detailing and construction. In many cases, the engineer can extend the life span of a building structure by utilizing simple repair/strengthening techniques. The choice of the repair/strengthening technique becomes,

Hybrid Techniques for RC Column Strengthening

SP-253: Fifth ACI/CANMET/IBRACON Int'l Conference on High-Performance Concrete Structures & Materials, 2008
Strengthening techniques of reinforced concrete structures have significantly changed in recent years. Such improvements happened mainly because of the development of new materials and their associated strengthening techniques. For example, polymeric composites of synthetic fibers (carbon, aramid, glass, etc.), high-strength concrete, and other high ...

Assessment of the seismic behaviour of RC columns

Engineering Structures, 2007
Current codes for earthquake resistant design of RC structures include several provisions that ensure satisfactory behaviour of columns. In order to check the efficiency of relevant code provisions, the behaviour exhibited by tested RC columns is assessed. For this purpose, experimental results on more than 450 RC columns were collected.

Flexural strength of FRP-confined RC columns

2002
Experimental tests on cylindrical specimens have underlined the effectiveness of FRP-based confinement systems; tests conducted on cubic samples have also pointed out the reduction of the confinement effectiveness due to the high stress concentration in the corners; it has been observed that such effect becomes lower as the corner radius increases (i.e.

Reliability Assessment of RC Column under Stochastic Stress

Journal of Structural Engineering, 1991
The reliability of a short reinforced concrete (RC) column subject to various loads is assessed. The loads yield a two‐dimensional stress, axial force N and bending moment M. Methods for solving such kind of problems are reviewed: Monte Carlo simulation is proved to be suitable. With reference to the lower‐end section of the column, the point NS, MS in

Strengthening of RC Wall-like Columns

"SP-200: Fifth CANMET/ACI Conference on Recent Advances in Concrete Technology-Proceeding, Fifth International Conference", 2001
In recent years, increasing efforts have been geared toward enhancing the axial load-carrying capacity of wall-like (i.e. high aspect ratio) reinforced concrete columns commonly used in building estates in Singapore. Although it has been proven through experimental results that composite fiber wraps are effective in strengthening round and square ...
