For example, a 6m × 6m × 1.5m foundation with concrete density 24 kN/m³ yields:

): Wind forces acting on the boom and mast, plus dynamic braking forces. Out-of-Service Condition (Crane Parked) Weight of the crane and counterweights (no hook load). Moment ( M2cap M sub 2

The maximum pressure must be less than soil bearing capacity. For the example above:

Crane manufacturer load data (In-Service vs. Out-of-Service). Step 2: Stability Checks (ULS - Ultimate Limit State) Tower Crane Foundation Design Xls

The crane mast anchors directly into the building's permanent raft foundation or a thickened structural slab. 4. Key Design Calculations

However, a spreadsheet is only as good as the inputs it receives. Garbage in equals garbage out—or worse, a collapsed crane. For example, a 6m × 6m × 1

) at the face of the crane mast to resist the bending moments. Check the beam shear capacity at a distance (effective depth) from the face of the mast.

Tower cranes are the backbone of modern high-rise construction, lifting thousands of tons of materials daily. However, the safety of the entire construction site relies on the structural integrity of the crane's foundation. A single foundation failure can lead to catastrophic structural collapse, financial ruin, and loss of life.

), the pressure under a gravity pad is non-uniform. The eccentricity ( ) of the resultant force is calculated as: For the example above: Crane manufacturer load data

This is where the (Excel Spreadsheet) becomes the most crucial tool in a site engineer’s arsenal. This article provides a deep dive into what these spreadsheets do, why they are superior to guesswork, and how to leverage them for pad, pile, and block foundations.

Mandatory in weak, cohesive soils, high water tables, or when crane heights induce extreme moments. C. Embedded Anchor Base (Fixing Angles)
