Shall we just include the controlling hinge in the model? or shall we include all possible failure modes?
Perhaps for linear analysis it does not really matter, but for nonlinear analysis it could....
we should double check both cases and conclude on this matter.
Model 160109_M1.sdb is the refined element model used to obtain the axial forces happening at the bottom of each pier. Groups were assigned and created and sections cut were defined using those group definitions.
Model 160109_M2.sdb is the equivalent model which needs to be updated so that the levels of axial forces in the piers are similar to those found in the previous model. One interesting finding is that the cross sections still have 12 inches as width, which is wrong. All sections in Wall 1 should have width=8 in or less.
What if we obtain the axial forces from the model without plastic hinges? Check Model 160109_M3.sdb ====> The previous model was correct!. It is that I was measuring the axial force in the wrong location. so now we go back to work with 160109_M2.sdb.
