Refering to Example 26 in SEAOC Vol 1 2009 pg. 102
Could use some expert clarificaiton...
When calculating the required strength for a column, overstrength required, they subtract Ev from Emh per ASCE 12.4-6, and then subract Em from 0.9D per ASCE 2.3.2 yielding tension of 205kips.
However, using ASCE 12.4.3.2 eq 7. yields 223 kips by subracting Ev from 0.9D first.
Which is correct or what am I missing? Is Ev supposed to reduce the overall seismic effect as it does in their example? Or should Emh be +/- and they missed it?
Thanks in advance.
