PCACOL (Columns, Load Input)
(OP)
I'm using PCACOL, ver. 3.00. I have a general question. In the load input section of the software, it has options to input moments at top and at the bottom of col.
If I have let say 50 k-ft moment at the top, and a 10k lateral load at the top of a 20 ft col., should I enter the bottom moment as (50+10*20=250 k-ft)? or just the moment due to the lateral load (10*20=200 k-ft) and the software will internally adds the top moment?
I appreciate your input as usuall.
Thanks,
Mansour

RE: PCACOL (Columns, Load Input)
for example, if your column is a "flag pole" with a concentrated moment at the top as well as a lateral force at the top, then the moment reaction at the base would be M + PxL. The program probably needs this moment reaction to determine moment magnification. Be careful of the sign because double curvature can be much different than single curvature.
good luck.
