Hello,
I am a bit confused in application of seismic load effects and have a few basic questions. For example lets say I have a 10'x10' shear wall that has a 10 kip unfactored seismic load at the top with a 1 k/ft dead and 1 k/ft live distributed load.
Q1: Should I only use 1.2D+1.0E+1.0L and 0.9+1.0E LCs?
Q2: E in this case will be rhooQe +.2SdsD. Does this mean E = 1.0(or 1.3) x 10 kip + (1.2+0.2xSDS)x(1kip/ft x 10'), or E =1.0(or 1.3) x 10 kip and D = 1.2D + 0.2xSdsxD. Basically where is 0.25SdsD added?
Q3: Should I use the rhooQe +.2SdsD anytime I use load combinations that have E and SDS>0.125?
Q3: When using OmegaQe +.2SdsD and my building rhoo is 1.3, Can I use 1.0E with omega and not 1.3E??
Q4: When should I use rhooQe or OmegaQe and with what load combinations?
Any input will be very much appreciated.
Thank you,
Victor.
