Maya smiled. "Four minutes, including the re-run."
The hardest part was . In a mat, every column tries to punch through the slab like a fist through a cardboard box. Maya wrote a Visual Basic for Applications (VBA) function called CheckPunchingShear(col_load, col_dim, d_effective) . It iterated through every column, calculated the critical perimeter, and spat out a utilization ratio. If any ratio exceeded 1.0, the entire sheet froze until the user increased the mat thickness. mat foundation design spreadsheet

Input soil layer data (depth, Es, ν, Cc). The spreadsheet calculates immediate settlement (typically 0.5 to 1.5 inches for sands) or consolidation settlement (1 to 3 inches for clays). Verify against project limits (e.g., total settle < 2 inches, differential < 0.5 inches). Maya wrote a Visual Basic for Applications (VBA)
