Hi, I’m dealing with Seismic Anchor Movements and B31E and i need some help.
I’m running my model under Dynamic Analysis module, Earthquake (spectrum).
For seismic evaluation, B31E has two condictions:
1) PD/4t+0.75i(Msustained+Mseismic)/Z<= min(2.4Sh,1.5Sy, 60ksi)
2) Fsam/A<=Sy
I understand condition 1 can be evaluated using a Load Case combiniation, S1(W+P1(SUS)) combined with D1 in the Static/Dynamic Combinations tab.
How can i evaluate condition 2? Should i evaluate only SAM effects? in this case how can i get this effects without inertial effects?

Thanks,

JPB
