I am a mechanical engineer, i am using Staad but i don,t know too much about LRFD codes, So it is necessary to learn the codes or staad automatically applt the bending moment capacities, shear capacities to the structure? I know theratically how to calculate the bending deflection and shear in a beam but i don,t know how much is the capacity of my beam for shear , bending and deflection, so i just chose LRFD code and select check code command and assign it to the structure and Got a table for utilization ratio.i want to confirm that if ratio is below 1, is structure is safe for bending and shear??
Thanks,
I am waitng for your response.
