Reliability Assessment of RC Column under Stochastic Stress
Journal of Structural Engineering, 1991The 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

CFRP-Confined Square RC Columns. I: Experimental Investigation
Journal of Composites for Construction, 2012AbstractThe majority of experimental studies investigating the stress-strain behavior of square concrete columns confined with carbon fiber-reinforced polymer (CFRP) composites have focused largely on unreinforced columns of small size. Research on the influence of larger cross section, height, internal steel reinforcement, and initial damage on the ...

Column–joint assembly in RC columns strengthened by steel caging
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2008The 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.

Cyclic Behavior of Nonconforming Full-Scale RC Columns
Journal of Structural Engineering, 2014Capacity models to assess structural safety are primarily based on experimental outcomes typical of new constructions. In order to analyze deformation and strength mechanisms of members that do not comply to current seismic codes and practices, an experimental investigation was undertaken on full-scale columns reinforced with deformed or plain rebars ...

Creep Analysis of Eccentric Compression RC Columns
Applied Mechanics and Materials, 2014Based on the elastic-creep theory, a series of expressions that describe stress-strain increment and corresponding recurrence formula of reinforcement and concrete are derived from some basic formulas for eccentric compression RC columns. The stress-strains changing process considering repeated loading is calculated through numerical method. The effect

Hybrid Techniques for RC Column Strengthening
SP-253: Fifth ACI/CANMET/IBRACON Int'l Conference on High-Performance Concrete Structures & Materials, 2008Strengthening 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 ...

Numerical simulation of steel plated RC columns
Computers & Structures, 2004Abstract A numerical model is described in this paper that can analyse a cantilever beam/column member with partial interaction plating under lateral loading. This type of analysis is complicated due to the relative movement, or slip, that occurs at the interface between the concrete and plate elements.

Rehabilitation of RC columns using ferrocement jacketing
Construction and Building Materials, 2018Abstract An experimental investigation on the effectiveness of ferrocement jacketing for rehabilitation of square and rectangular RC columns preloaded with a fraction of its ultimate load carrying capacity has been carried out. The corners of the columns were rounded for improving the effectiveness of confinement.

Strengthening of RC Wall-like Columns
"SP-200: Fifth CANMET/ACI Conference on Recent Advances in Concrete Technology-Proceeding, Fifth International Conference", 2001In 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 performance of bond controlled RC columns
Engineering Structures, 2008Abstract An experimental investigation was carried out to examine the enhancement of seismic performances of reinforced concrete (RC) columns such as shear strength and ductility by controlling the bond of longitudinal reinforcements. Four 300×300 mm square RC columns with ordinary bonded reinforcements and completely unbonded reinforcements were ...
