Indian Concrete Journal - ICJSummary: Reliability analysis for rectangular reinforced concrete columns has been evaluated with varying live loads. The deterministic approach using the SP: 16 (1980)[17] code is carried for a corner column subjected to axial force and biaxial moments. A typical reinforced cement concrete (RCC) frame is modelled in the ETABS software with geometrical, material, and live load variations. The percentage of rebar of a column is taken from the software tool. The work is conducted for two different orientations of columns in plan and it is presumed that if the rebar percentage obtained after considering the randomness in design parameters exceeds the rebar percentage calculated from the deterministic approach, then the column is said to be in failure. A Monte Carlo simulation technique was employed in the evaluation procedure to predict the probability of failure of the column. A random number generator in excel is employed in order to generate random variables. The randomness in variables relating to geometrical dimensions, material properties, and loading are considered. The study investigates the reliability of the column when design variables are random in nature, and it also extends the plotting of the histogram, probability distribution function, and probability plot.
