1. Project Title:   Analysis of Jacketed Reinforced Concrete Column Subjected to Uni-Axial Load & Bi-Axial Load

.AbstractJacketing of reinforced concrete column is to target the improvement of local vulnerabilities in columns related to

inadequate strength (compressive & Flexural) or poor ductility. Theoretical analysis have been carried out in the

present study for different column sections of jacket thickness of 50 mm and 100mm and 150 mm for jacketed RC

columns subjected to uni-axial compressive loading.

The uni-axial load carrying capacity along the major axes has been carried out under balanced section condition.

Nonlinear finite element analysis has been carried out for the jacketed RC columns to compare the confined

concrete strength (fcc) of finite element analysis with that of theoretical analysis, to plot the variation of stresses at

the central core concrete and at the interface of old and new concrete. Considerations have been given for

variations in the properties of different types concretes used in the jacket and the original column.

In order to find out the increase in the confined capacity of jacketed columns due to strengthening with respect to

original column, theoretical analysis has been carried out.

The biaxial load is computed by using Bresler’s reciprocal load equation. The concentric load carrying capacities

have been carried out based on the sheikh and Uzumeri’s confined concrete model. The uni-axial load carrying

capacity along both the axes (major and minor) has been carried out under balanced section condition. ANSYS is

used for the FEA analysis.
