RAM Concrete Analysis - Column Load Comparison with Hand Calculations

When comparing your hand calculations of column loads with those reported by Ram Concrete Analysis - Column Design Forces, firstly one needs to run the model with Live Load Reduction switched off as he has might have tried to compare the values of Live Load, with Live Load Reduction applied, taken from the RSS to hand calculations with no Live Load Reduction taken into account. If you run the model with Live Load Reduction switched off you get a value closer to the hand calculations.

Secondly, the area assumed may seem high as the core walls (if any present nearby) will attract a lot of load. One needs to remember that load will be distributed based on the stiffness of the members, in which case more load will be attracted to the cores than the columns.
