- When an edition’s chart has no value, the page says it uses plate analysis and identifies that in the result.
Field notes
The page distinguishes chart-derived values from cases handled by plate analysis, and says the result identifies when that fallback is used. Its support options include four sides, three sides with one free edge, two opposite edges, and a one-edge cantilever; the stated chart ranges vary by support and edition. A thickness override can be entered, while leaving it blank uses the listed E1300 Table 4 minimum.
