dear all.
i want to ask about the RATIO command in API code in Staad pro v8i.
i use Staad Pro v8i SERIES 4. in AISC, the RATIO command means "Permissible ratio of actual to allowable stress". but in API, it says "Permissible ratio of applied loading to section capacity".
AISC
API
i did study to compare using the RATIO command under API code.
case 1 : i use RATIO 2.06
case 2 : RATIO 1 (default)
it's the same staad file. but when i change the RATIO to default, the actual ratio shows totally different from case 1.
anyone know why this is happen ?
basically if i use the RATIO command under AISC code, it won't show any different actual ratio. only the normalized ratio.
thank you.
