Gents,
today i'm working on pipe/tubular section in my model. to check the ratio in analysis, i'm using API code, but for non tubular section, i use AISC 9th Ed.
however, i have some question regarding API code. (i use STAAD Pro v8i SELECT 4 20.07.09.31)
in API design parameter :
1. BEAM command
BEAM
1.0
Beam parameter:
0.0 = design only for end moments or those at locations specified by the SECTION command. 1.0 = calculate moments at twelfth points along the beam, and use the maximum Mz location for design. 2.0 = Same for BEAM 1.0, but additional check is made at each end.
0.0 = design only for end moments or those at locations specified by the SECTION command.
1.0 = calculate moments at twelfth points along the beam, and use the maximum Mz location for design.
2.0 = Same for BEAM 1.0, but additional check is made at each end.
BEAM 1.0
when i use BEAM 2.0 ALL -> it shows ERROR.
PARAMETER 6CODE APIBEAM 2 ALLRATIO 1.33 ALLLOAD LIST 4CHECK CODE ALLFINISH
why it says ERROR ?
if i use BEAM 1.0 ALL, what's the different between BEAM 1.0 in AISC 9th Ed ?
2. MAIN Command
MAIN
0.0
Design for slenderness.
1.0 = Main member 2.0 = Secondary member
1.0 = Main member
2.0 = Secondary member
could you explain to me what is main and secondary member means ? In API RP 2A-WSD code they say secondary member is stair/ladder , boatways, etc.
otherwise will be as primary member.
but i'm not really sure if this is the same just like STAAD do.
your explanation is highly appreciated.
Thank You all.
