The ground must support the weight without settling. For a shallow pad footing, the pressure distribution is usually trapezoidal or triangular due to the massive overturning moment. The maximum and minimum soil pressures ( qmaxq sub m a x end-sub qminq sub m i n end-sub ) are calculated using the flexure formula:

IF(FOS_Overturning >= 1.5, "PASS", "FAIL") (Note: Some regional codes require a factor of 2.0). C. Safety Factor Against Sliding

Your Excel spreadsheet should reference applicable codes: Tower Crane Foundation Design Xls

Using spreadsheets for this critical design task has clear strengths and limitations. Understanding these is key to using them effectively.

This does not make the spreadsheet obsolete. Rather, it transforms its role. The future will likely see spreadsheets used as or custom verification tools working alongside more powerful software. An engineer might use FEA for global analysis, then export key load cases into a custom-designed Excel spreadsheet to perform a specific code check or optimize reinforcement layout, providing an agile and transparent tool for specific tasks. The ground must support the weight without settling

Utilized across Europe and the UK, incorporating Limit State Design (ULS and SLS) and partial safety factors for load and soil combinations.

When programming or using a design spreadsheet, engineers follow a strict sequence of calculations: This does not make the spreadsheet obsolete

A shallow, heavy concrete block used when the upper soil layers have a high bearing capacity. This design relies entirely on its own dead weight to resist overturning moments. Piled Foundation

The soil must be able to support the high concentrated pressures, often requiring an allowable bearing pressure of 180-300 kPa depending on the site. 🏗️ Common Foundation Types
