Shear Capacity of Lightly Reinforced Concrete Columns
The columns with light confinement are common in current detailing practice in many developing countries. Nevertheless, the available shear strength formulas at many codes are generally developed for regular reinforced concrete columns that tend to ever-estimate the shear strength capacity. A semi-empirical analysis has been conducted to investigate the flexure-to-brittle transition due to the shear strength degradation for lightly confined columns. The principal stress at the cracked area of concrete as the function of the ductility level of columns has been used to develop the model. A set of database collected from previous studies has been used to verify the model on estimating the shear strength of reinforced concrete columns at lateral load failure. As a result, the model provided good agreement with the experimental data and is useful to be applied in practical design or in analyzing the seismic performance of such columns.
