To adequately address these new performance requirements, a rational and cost-oriented policy is needed to help building managers and owners make fiscally intelligent decisions regarding the retrofitting of existing structures. This paper presents a cost-rationalized approach to blast-mitigation retrofitting decision making, with respect to a building’s criticality to the surrounding community. The proposed method addresses current approaches to blast assessment, typical blast-related vulnerabilities (structural and non-structural), and possible solutions for vulnerability mitigation. Special emphasis is given to non-gravity based loadings, post-incident functionality requirements, and transient versus permanent/semi-permanent loading.335933 bytesapplication/pdfenBlast mitigationExplosivesStructural retrofittingTerrorismCost analysisBuildings--Blast effectsBuilding, Bombproof--Cost effectivenessBuildings--Repair and reconstruction--Cost effectivenessConference Publicationhttps://creativecommons.org/licenses/by-nc-sa/1.0/
