Experiments and Modeling of Structural Steel Elements Exposed to a Fire. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5B) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Anthony P. Hamins, Alexander Maranghides, Kevin B. McGrattan, Erik L. Johnsson, Thomas J. Ohlemiller, Michelle K. Donnelly, Jiann C. Yang, George W. Mulholland, Kuldeep R. Prasad, S R. Kukuck, Robert Anleitner, Therese P. McAllister
Reconstructing the fires and their impact on structural components in the World Trade Center (WTC) buildings on September 11, 2001, requires extensive use of computational models. For the use of such models to be a viable investigative tool, it is

Author(s)
Kuldeep R. Prasad, Howard R. Baum
The collapse of the World Trade Center towers on September 11, 2001, resulting from a combination of aircraft impact damage and subsequent fires, was studied as part of the Federal Building and Fire Safety Investigation of the WTC Disaster. This report

Passive Fire Protection. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-6A) ***DRAFT for Public Comments***

September 1, 2005
Author(s)
Nicholas J. Carino, M A. Starnes, John L. Gross, Jiann C. Yang, S R. Kukuck, Kuldeep R. Prasad, Richard W. Bukowski
This report deals with the passive fire protection used in the World Trade Center (WTC) towers. The main objective is to provide background information that can be used to assess the in-place conditions of the passive protection before and after aircraft

Reconstruction of the Fires in the World Trade Center Towers. Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1-5) ***DRAFT for Public Comments***

The collapses of the World Trade Center towers on September 11, 2001, resulted from a combination of aircraft impact damage and the ensuing fires. This report documents: The information obtained on the factors that affected the nature, duration and

Coupled Fire Dynamics and Thermal Response ofComplex Building Structures

July 30, 2005
Author(s)
Kuldeep R. Prasad, Howard R. Baum
Simulation of the effects of severe fires on the structural integrity ofbuildings requires a close coupling between the gas phase energy release andtransport phenomena and the stress analysis in the load bearing materials.The connection between the two is

Fire Performance of Partition Assemblies

Samuel L. Manzello, Richard G. Gann, S R. Kukuck, Kuldeep R. Prasad, Walter W. Jones
For nearly a century, the cornerstone of fire safety in buildings has been the ability to confine a fire for a time sufficient for people to reach safety and for successful fire suppression activity. To effect this, the partitions in a building (walls

Kevin B. McGrattan, Howard R. Baum, Ronald G. Rehm, Glenn P. Forney, Kuldeep R. Prasad
Scientists and engineers are often asked to make predictions of the state of technology in the future and are usually laughably wrong. The best prognosticators get the trends right, but cannot possibly fill in the details. Think of Jules Verne predicting a
