GBP Calculator / The experience
See the whole picture.
A visual workspace for ground bearing pressure. Understand the arrangement you are checking, from the applied load to the ground beneath it.
Your arrangement, in view
Explore the load, timber mat and ground in an interactive 3D view. Drag the Perspective view to rotate the support. Change dimensions and see the geometry respond. Choose Section for a side view or Layers to separate the parts. These views are schematics of the model, not detailed construction drawings.
Four stages. One support.
Support lab follows four stages: LOAD for the force and ground capacity, SUPPORT for the mat dimensions, TIMBER for the material properties, and RESOLVE to review and calculate. Enter exact values directly, with units beside every field. Return to any input stage from the navigation rail.
Four checks, one clear answer
In RESOLVE, read the pressure on the ground and the length of mat that participates in the calculation. The model stays with the results as you inspect ground bearing, timber bending, timber shear and relative edge deflection separately. Select a check to see its explanation and model view. A failed check stays visible instead of disappearing into an overall score.
Change it. Check it again.
Select Edit inputs to return to the controls. When an input changes, the earlier result is removed. Run the analysis again to check the new arrangement. The calculator keeps the difference between a configured model and a calculated result clear.
Built for the working day
The workspace adapts to desktop and phone screens. English labels and imperial units stay consistent throughout: ft, lb, psf, psi and ksi. A print view records the calculated results and the inputs used.
