This spreadsheet is an educational module that shows how axial and flexural stresses are combined to produce a nominal and design strength curve for a rectangular reinforced concrete column. A detailed explanation of the calculations are given in Columns Example 1. This content of this spreadsheet is separated into several sheets by topic. To navigate to the different topics, select the tabs at the bottom of the page.
Input fields have a blue background. The rest of the cells in the spreadsheet are locked but the formulas in the cell are visible for the users information. A brief description of the topics are provided below:
This spreadsheet analyzes rectangular columns with ties. The analysis is for one axis along the "h" dimension. The number of layers refers to the number of bars in the "h" direction. Layer 1 is always placed as close as possible to the face of the concrete that creates the greatest value for "d." If two layers are entered, the next layer is placed as close as possible to the face of the concrete that creates the lowest value for "d." For more than two layers, the additional layers are evenly spaced between the outer layers and numbered in order from the greatest value of "d" to the lowest. The bar geometry must be symmetrical about the center of the section. The remaining inputs are self explanatory. Note that one value of fy is used for both the longitudinal and transverse reinforcement.
