How many more columns could be removed and the buildings still stand?
When we did our preliminary stability analysis for WTC 1, we removed up to eight columns from the core in the model, and the building remained standing. Q: There are uncertainties in these calculations. You can’t see inside the buildings. Could more core columns have been broken in WTC 1 than WTC 2? Or could none have been severed? Are they definite impossibilities? A: We tried to use parameters in the model in the best way that we know them. We spent a lot of time to model the geometry, material properties, and the failure criteria correctly. We understand that these are subjected to uncertainties and tried to bound the case. We are trying to complete additional studies to confirm our model results. C: This project has done a lot of excellent work. You and your team should be congratulated. You need to be clear about uncertainties in your report. I am concerned that there will not be any technical topic reports for this project. I recommend that technical topic reports be included for
