One more update before we wrap up 2025. We've added a new calculator to handle a design scenario that typically requires custom spreadsheets or digging through research papers.
Point Load on Slab on Grade Calculator now available
Designing isolated column loads on concrete slabs just got simpler. The new Point Load on Slab on Grade Calculator handles concentrated loads to ACI 318-19 without requiring custom spreadsheets.
Since this design scenario isn't explicitly covered in ACI code scope, engineers have traditionally relied on structural research articles like the Shentu method or built their own calculation tools. Now you can design these directly in Calcs.com with a validated workflow based on established structural research.
The calculator covers common applications including:
- Free-standing mezzanine columns
- Heavy equipment supports on warehouse slabs
- Column base plates and racking loads
- Other concentrated loads on slabs-on-grade
You get full capacity checks and design verification in a documented, code-compliant format. No more maintaining separate spreadsheets or searching through research papers mid-project.
Whether you're designing industrial facilities with heavy equipment or commercial spaces with mezzanine structures, the calculator delivers the analysis you need to keep projects moving forward.
