Modeling of RC columns strengthened with RC jackets

Earthquake Engineering & Structural Dynamics, 2011
AbstractConstructing concrete jackets is a common technique when strengthening reinforced concrete (RC) columns, particularly in seismic regions. However, there are many uncertainties concerning the behavior of the composite specimen, particularly at the interface between the old and new concrete.

Fire resistance of RC and FRP-confined RC columns

Magazine of Concrete Research, 2006
The retrofit of columns by fibre-reinforced polymer (FRP) confinement has become a popular technique over the past decade but when this technique is adopted to strengthen reinforced concrete (RC) columns in buildings, the fire resistance of the strengthened column is often a serious design concern.

Reliability Evaluation of RC Columns

Journal of Structural Engineering, 1999
This paper presents an approach for the reliability analysis of the RC columns considering the correlation between the axial load and bending moment or the uncertainty in the load eccentricity. The reliability analysis is based on the efficient first-order reliability method and uses the inverse normal transformation to deal with the modeling error ...

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.

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

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.

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.
