Strength Evaluation of Deteriorated RC Bridge Columns

Journal of Bridge Engineering, 2008
Condition-rating methods followed by load rating calculations are used for evaluating existing bridges in the United States. Ratings are assessed visually based on engineering expertise and experience, and in some cases supplemented by nondestructive tests. Good understanding of the effects of deterioration on the structural performance leads to better

Retrofitting of fire damaged RC columns

Proceedings of the 11th International Conference on Structures in Fire (SiF2020), 2020
The post fire (residual) capacity of Reinforced Columns (RC) members descends drastically due to degradation of concrete strength, permanent deformation and damage (spalling or buckling of rebar’s) in the column. The restoration of such members is essential immediately after the fire event in case of important structures and /or where some part of the ...

Review on Seismic Behavior of RC Columns

Applied Mechanics and Materials, 2013
Column is the key member of the seismic structures, after the earthquake destroyed, not only cause column serious economic damage, and will cause a large number of casualties. For studying the seismic behavior and size effect of full-scale reinforced concrete columns.

Retrofit of RC square short columns

Engineering Structures, 2005
Abstract There exist many reinforced concrete short columns that are vulnerable to brittle shear failure as repeatedly demonstrated during recent severe seismic events. Due to the large scale of the problem, it is important to investigate the behaviour of short columns and approaches to their retrofit.

Investigation into FRP repaired RC columns

Composite Structures, 2003
Due to the aging of the infrastructures in the US, repair and rehabilitation of damaged steel reinforced concrete structures using fiber reinforced plastics (FRP) are increasingly becoming a topic of interest in the infrastructure community. In this study, a finite element analysis using ANSYS® was utilized to conduct a parametric analysis. Experiments

Comparative Study Of RC Column With RC Jacketing And FRP Jacketing

International Journal on Science and Technology
Retrofitting of existing reinforced concrete (RC) structures has become increasingly essential due to ageing infrastructure, evolving seismic design requirements, and performance deficiencies identified during structural assessments. Among the various strengthening methods, RC jacketing and fibre-reinforced polymer (FRP) wrapping are two of the most ...

Instability of Longitudinal Bars in RC Columns

Journal of Structural Engineering, 1988
The collapse of reinforced concrete structural elements subjected to compression is linked to the instability of the reinforcement bars. This phenomenon may occur in the longitudinal region between two consecutive hoops, or may involve a number of hoops, deforming them through tension until they fail.

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.
