Parameter input guide
Use the circled i controls for units, source meaning and input guidance. Enter factored actions for the selected section. Reinforcement area is derived from bar count/diameter or spacing, not entered directly.
Enter actions for the assessed strip width. Area per metre and actual strip area are both shown to expose the source unit mismatch.
Scope and limitations
Source sheet is named Wall(2004) but labels2013. Its per-metre reinforcement, selected-width demand, overall-depth lever-arm cap and link exponent are not a verified design method. Fire cover lookup is for continuous slabs, not verified wall fire resistance.
