Floor Load Capacity Checker
Compare planned equipment/storage loading against the floor's design rating.
Area-average passing is necessary but not sufficient — point loads (machine feet) also need punching and local-bending checks. Steel spreader plates are cheap insurance.
Formula
Floor Load Capacity Checker is a free floor load capacity for structural engineers, fabricators and site engineers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Floor Load Capacity Checker
Compare planned equipment/storage loading against the floor's design rating. The calculation implements p = W·g/A vs rated kN/m² (IS 875 Part 2; building floor-load certificates). Area-average passing is necessary but not sufficient — point loads (machine feet) also need punching and local-bending checks. Steel spreader plates are cheap insurance.

Frequently asked questions
What formula does the Floor Load Capacity Checker use?+
It computes p = W·g/A vs rated kN/m², per IS 875 Part 2; building floor-load certificates. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
Area-average passing is necessary but not sufficient — point loads (machine feet) also need punching and local-bending checks. Steel spreader plates are cheap insurance.
Can I use this for real structural design?+
It implements the exact textbook/code formula cited below the result and is ideal for sizing, checking and learning. Final designs should be verified by a qualified engineer against the full code with all load cases.
Is the Floor Load Capacity Checker free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
