***NOTE: Equivalent Static Analysis should preferably be performed for regularstructures with approximate natural time period less than 0.4s and regularstructures with height less than 15m in Seismic Zone II. Ref Cl.6.4.3 and 7.6BASE SHEAR AND TIME PERIOD IN Z
why i am getting this warning?
This is not a warning and just note to remind the conditions for which you should using equivalent static analysis method. If you found that the conditions are not met in your model, you should go for response spectrum load case.
