Good morning, everyone! !
I am learning to use straus7 independently and I have difficulties in carrying out a seismic analysis.. to be sure that what I am doing is correct I list the steps I followed:
1) creation of the model and load combos, including a seismic comb that considers g1+g2+ψ2*qk;
2) insertion of the response spectrum (sd-t) into tables;
3) performed a linear static to have the starting data;
4) performed a natural frequency with initial condition those relative to the sysmic comb of the linear static (to have the mass given by g1+g2+ψ2*qk);
5) performed a spectral response analysis starting from the newly calculated frequencies by putting in the direction vectors the combs [Per esempio, partendo dallo spettro inserito, 1*X+0,3*Y+0*Z (Come da NTC08)].
a) is the procedure adopted here correct or forget something?
b) at this point how do I combine stresses with those calculated in linear static?
b) how do we consider accidental eccentricity of 5% to consider torque effects?
Sorry about the odd banality I asked but I have no example available. .
Thank you and good day!
