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.

Effects of cross‐sectional shape on the reliability of RC columns

Structural Concrete, 2011
AbstractThis paper studies the effects of cross‐sectional shape and rebar configuration on the reliability indices of concrete columns. Three sections with rectangular, square and circular shapes are selected. Using the Monte Carlo simulation technique, the statistical parameters for reinforced column resistance are calculated along several load ...

Optimum design of uniaxial RC columns

2014
For reinforced concrete (RC) column members, the distance from extreme compression fiber to neutral axis (c) is depended to combinations of axial load and flexural moment. Since c is depended to different internal forces, the value of c cannot be found for both objectives.

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 ...

Seismic Capacity Reduction Factors for a RC Beam and Two RC Columns

2018
Many building structures can be damaged and even collapse during a severe earthquake. For this reason it is important to take immediate decisions about the safety of damaged structures in order to avoid possible human losses in case of aftershocks.
