Divide the stabilizing moments (caused by the weight of the concrete and soil overburden) by the overturning moments. The safety factor must typically be greater than 1.5. Tower Crane Foundation Design Xls

) and ensures the pressure exerted does not exceed the allowable soil bearing capacity.
Your design is only as good as the ground it sits on. An effective XLS tool allows you to plug in Geotechnical Investigation Share public link Divide the stabilizing moments (caused
These spreadsheets calculate fundamental parameters such as foundation size, embedment depth, pile capacities, and reinforcement requirements. They typically reference internationally recognized standards for design verification, including:
Because overturning moments are exceptionally high, the resultant vertical force rarely acts exactly in the center of the footing. The eccentricity ( ) is calculated as:
Allows engineers to rapidly iterate dimensions ( (In-Service) and (Out-of-Service)
What (or maximum overturning moment) are you designing for?
Once loads are established, the spreadsheet guides the engineer through iterative sizing calculations:
This is a large, heavy block of reinforced concrete poured directly onto stable ground. It relies on its sheer self-weight to resist the overturning moment and prevent tilting. It is cost-effective but requires high-bearing-capacity soil. Pile-Supported Foundation
