Dear all,
I've searched a lot, but still couldn't get an idea what is the appropriate loading case or combination to get the values of P and V while defining auto hinge for pushover analysis in etabs or sap2000.  P and V values are required as per the table 10-7, 10-8 of ASCE 41-13, table 6-7, 6-8 of FEMA 356 and table 11-3, 11-4 of ATC 40.

For each column the P value can be maximum due to different load combinations. So does it mean that I have to know which combination gives max. P in each column and assign different auto hinge for each column? Also the case/combination for maximum value of V can be different from P. In this case how can we assign only one load case/combination for both P and V values.

For beams, maximum V values result from the ductility requirements due to sway and hinge formation in beams and not from load cases/combinations.

I would really be grateful if somebody could give me an insight to which load case/combination is appropriate of P and V values while defining auto hinge for pushover analysis in etabs or sap2000.

Please see the picture attached.

Thankyou,
