On October 11, 2013, the Defense Threat Reduction Agency (DTRA) awarded PEC a contract for “Collateral Building Damage due to Nuclear-Induced Airblast” under the Nuclear Weapons Effects Network (NWEN) BAA. The objective of the “Collateral Building Damage due to Nuclear-Induced Airblast” program is to develop a probabilistic, physics-based model for the fragmentation of building components subjected to airblast from the detonation of nuclear and large conventional weapons in an urban environment. The range of façade and structural damage extends from complete brisance near ground zero to distances at which the structure survives but the façade fails, and from the end of that range to distances at which the façade and structure are undamaged. For both ranges, the failure of the façade materials presents collateral damage hazards to both buildings and personnel. The resulting fragmentation model will be instrumental in predicting collateral effects on other buildings and on personnel. This project will advance the state-of-the-art in two critical areas: (1) prediction of material and structural level debris fragments from nuclear and large conventional weapon detonations in an urban environment and (2) development of test data for building components and materials subjected to simulated nuclear airblast loading.

PEC has teamed with SciRisq, Stanford Research Institute (SRI), Johns Hopkins University (JHU), and Sam Kiger for the project. SciRisq will be providing nuclear airblast modeling capabilities, SRI will be providing fragmentation experimental work, JHU will be simulating fragmentation on material level scales, and Sam Kiger is providing nuclear blast effects to structures expertise.  This program further exhibits PEC’s expertise in blast effects to structures and PEC is proud to have the opportunity to develop cutting edge research results for DTRA.
