Amrose Associates was appointed to verify the structural performance of a steel crane spreader mat to make sure it could safely distribute loads under varying ground conditions and operational scenarios.
The Challenge
Preliminary design calculations had been completed but further analysis was needed to confirm the mat’s load distribution capability and structural behaviour in real-world conditions. The design needed to perform safely across a range of ground scenarios, from soft compressible ground to very stiff support conditions.
Our Approach
We developed a detailed finite element analysis (FEA) model to assess the mat’s performance in terms of both strength and stiffness. The analysis identified that initial assumptions had overestimated the mat’s ability to spread load in one direction, highlighting the importance of detailed verification.
We assessed performance across varying ground conditions to evaluate:
- Bending stresses under soft ground conditions
- Compressive stresses and potential buckling under stiff ground conditions
- Load distribution behaviour and structural stability
All results were independently verified using hand calculations and checks to Eurocode 3 for reliable analysis.
The Outcome
Our work provided a fully substantiated assessment of the design, delivering:
- Verified structural performance
- Improved understanding of load behaviour
- Identification of critical stress conditions
- Confidence in safe operation across site conditions
The project demonstrates Amrose Associates’ expertise in advanced structural modelling, temporary works verification and the accurate interpretation of complex engineering behaviour.
