): Set an initial trial length. As a baseline rule of thumb, and never less than 8 feet (2.4 meters).
Formulas and outputs:
The is more than a computational tool—it is a structured representation of geotechnical engineering principles. Whether you are building one from scratch or customizing a template, focus on clarity, error-proofing, and full documentation of assumptions. mse wall design spreadsheet
): Multipliers that increase design loads (e.g., 1.5 for horizontal earth pressure, 1.75 for live loads). Resistance Factors ( ): Set an initial trial length
: Rather than a Factor of Safety, the spreadsheet must satisfy the limit state equation where factored resistance exceeds factored loads ( 5. Steps to Create or Use the Design Spreadsheet Whether you are building one from scratch or
