4. Design and Investigation using spColumn
spMats provides the option to export piles and columns information from the foundation model to spColumn. Column Text Input (CTI) files are generated by spMats to include the section, materials, and the loads from the spMats foundation model required by spColumn for strength design and investigation of piles. Once the spMats foundation model is completed and successfully executed, the following steps illustrate the design of a sample pile.

After exporting spColumn input files, the pile design/investigation can proceed/modified to meet project specifications and criteria.
