This report analyzes the global response of WTC 7 to fireinduced structural failures and the resulting sequence of component and subsystem failures to determine the events that led to the global collapse of the building. The analysis involved a finite element model of the entire building, which was developed in LS-DYNA. Preliminary work involved twostory and 14 story subassemblies. The 47 story global model was based on the original structural drawings as well as construction fabrication shop drawings for connections. The model included the primary structural components throughout the building, including exterior and core columns, floor framing beams and girders, floor slabs, column transfer truss structures, wind bracing truss members, and penthouse structures.
