Problem 450:
1- What load combination is this 1.2D+1.0E+1.0L besides they added both Roof live load "Lr" and snow load "S" even though you have to use only one of them in any load combination.
In the load combination they used 0.9D+1.0E, the dead load and seismic load supposed to be subtracted from each other not added to each other.
2- Why they did not include the SDS any load combinations?
In Foundation design:
1- No load combinations used even though there are 3 load combinations shall be used
2- The pedestal was not designed according to the SDC "D" , the hoops shall be completely different
Any Explanation.
Problem 460:
1- Why in the solution, the chord force was magnified by omega node? As far as I know Omega nods is used with drag struts not collectors, any explanation?
2- Why the solution did not consider at line "C" to determine the chord force, is this because there is no shear wall at that line?
Thanks
