NIST developed SAP2000 models of WTC towers 1 and 2. The models were obtained by an FOIA request. The data files are available at razor.occams.info/nist-wtc/.
Much of the data contained in the...
The objectives of this project include:
creating a model of a WTC tower
identifying scenarios for analysis
running analysis codes with the scenarios
validating the model and verifying results
