Provides design notes for different fire resistance classes (R15, R20, R30, R60) and tabulated support screw temperature ranges for RHS/SHS tube beam sections. Includes requirements to verify fire-protection thickness using Tcrit ≤ 600 °C for R30 and R60 validity, and states assumptions and applicability for R15 and R20, including protected cases.
