Wheel load dispersal to a patch
point_to_patch_dispersalThe Point to Patch Convertor's dispersal for one point load: the code's contact area (or the load-derived one), the spread through surfacing and slab to the mid-plane or neutral axis, the effective patch b_eff × l_eff and its pressure, with the clause. Presets cover EN 1991-2 LM1/LM2, the UK NA, CS 454 / HB, BS 5400 and Network Rail ballast/fill. Needs no model.

| Name | Required | Description | Default |
|---|---|---|---|
| b0 | No | Contact width across the traffic, m (null = the preset's). | |
| l0 | No | Contact length along the traffic, m. | |
| tc | No | Slab depth, m (apply: default the plate thickness). | |
| ts | No | Surfacing / ballast / fill depth, m. | |
| load | No | Point load, kN (needed for load-derived presets and the pressure). | |
| alphaC | No | Half-angle through the concrete, °. | |
| alphaS | No | Half-angle from vertical through the surfacing, ° (0 is honoured). | |
| presetId | Yes | Contact area and spread rule (EN 1991-2, UK NA, CS 454, BS 5400, Network Rail…; point_to_patch_read lists them with their clauses). | |
