Dear Members,
Please help me to learn about the problem BASE SHEAR CALCULATION ALONG GLOBAL Z DIRECTION IS NEGLIGIBLE.
I mention the brief information about my model as follows in pewit to point:.........
01) I create RC model in V8i SS6.
02) The frame of model is not fully orthogonal in X and Z axes.
03) Use Reference Load type Mass without -ve sign, Rigid Floor Diaphragm, UBC-94 Seismic definition
04) Provide Seismic weight by Reference Loads in X, Y. and Z directions with the factor 1 for DL and 0.5 for LL
05) I try to find out, a) Soft Story as per ASCE7, b) Story Shear c) Story Drift with Limit L/250
06) I provide Static Seismic Analysis.
My confusions in this model are...........
A). Why the Base shear calculation along Global Z direction is negligible?
B). Why the Story Shear is missing?
C).Am I right in the case of soft story checking?
Please, help to know me also, which are the out of my questions but helpful.
NB: For more information, I attached my STAAD file here. (Please visit the site to view this file)
Thanks
