Chapter 4: Reinforced Concrete Columns, Part 1
Description:
Reinforced concrete columns are often designed with the help of computer programs or tables or graphs. The tables and graphs provide the usable axial load and moment capacities over the complete range (from maximum axial load capacity at the minimum moment to zero axial load and maximum moment capacity). A separate chart or table must be generated for each combination of concrete and reinforcement strengths. Even when the graphs or charts are prepared in a non-dimensionalized form there are still an infinite number of possible combinations of reinforcement, column sizes and material strengths.
