Rapid Screening of Buildings for Blast Risk Assessment
WIT Transactions on the Built Environment, 2005
The risk of building against blast effects can be determined by means of a threat risk assessment (TRA). A TRA involves establishing the potential threat, determining the vulnerability of the building against the established threat, evaluating the consequence caused by the realization of the threat and finally assessing the risk of the buildings against the blast threat. A full TRA can be a time-consuming and costly undertaking, especially for owners of a large inventor of buildings. A rapid screening methodology has been developed for conducting a preliminary assessment of buildings against blast effects. The methodology accounts for the threat, the vulnerability of the building, the consequence of the vent and the risk, which is the product of the threat and the consequence. Rapid screening of one building should take no more than 2 days to complete. By ranking buildings according to their risk values, prioritization of buildings to undergo a full TRA can be established for determ...

Natural catastrophes are common in Indonesia, with earthquakes being the most destructive. This research aims to evaluate the vulnerability of government buildings in Kampar Regency using the Rapid Visual Screening (RVS) method. The observation was conducted in two office buildings of Kampar Regency: (1) the Economics, Development and Welfare Department and (2) the Governance, Law and Politics Department. According to the coordinates, the buildings assessed in this research are located in a high seismicity region. The results unveiled that both buildings had a potential vulnerability value greater than 2, indicating that the structures could be declared safe against earthquake risk using FEMA P-154, with an S value of 2.3. Vertical irregularity, plan irregularity, and soil type have become critical in calculating the FEMA P-154 assessment since they deduct value elements that might impact a building’s susceptibility to seismic risks.
Terrorism Prevention Measures for Office Buildings - a New Layering Approach
WIT Transactions on the Built Environment, 2005
This paper describes how terrorist targets have change over time from specific individuals, aircrafts and government or military related installations to office buildings. Considering recent terrorism attacks targeting office buildings the one that tops the number of victims is the September 11, 2001 World Trade Center attacks in New York. This terrorism incident, along with the threat of other attacks towards office buildings, has modified the perspective of owners and management companies towards security of office buildings in a post September 11, 2001 context in the U.S. The initial reaction, of general security measures with an unclear prevention role, should be replaced by improved and more thorough decision-making process of prevention measures targeting specific types of threats for specific buildings. This paper proposes the development of a layered approach in terrorism prevention through the formation of Building Security Task Forces (BSTF), which will utilize a number of...
Terrorism Risks and Blast Damage to Built Infrastructure
Natural Hazards Review, 2006
There is increasing interest in the use of risk management techniques for assessing vulnerability of built infrastructure to the "new" ͑man-made͒ hazard of terrorism. As such, the various uncertainties and risks associated with terrorism must be quantified and then used as the basis for assessing the viability and relative benefits of different mitigation measures, such as the use of blast-resistant technologies and other protective measures. In this paper, a probabilistic risk assessment procedure is developed to predict risks of damage arising from blast damage to built infrastructure. Issues related to risk assessment, including the concept of "risk transfer" and comparisons with natural hazards, are also discussed. To illustrate the concepts described, a preliminary reliability analysis is conducted, where fragility and blast reliability curves are developed for common glazing systems subject to explosive blast. The probabilistic analyses include the uncertainties associated with blast modeling, glazing response, and glazing failure criteria, and these are used to assess the effectiveness of various glazing systems.

The technical note considers the cost effectiveness of risk mitigation measures for protection of buildings to terrorist threats. Protective measures might include vehicle barriers, perimeter walls, blast resistant glazing, strengthened perimeter columns, etc. Indicative values of attack probability and characteristics of commercial buildings in the United States are described. The cost effectiveness of protective measures are calculated from a preliminary economic decision analysis that includes cost of the protective measures, attack probability, reduction in risk due to protective measures, and failure consequences. Economic risks due to terrorism are compared with risks from hurricane and seismic hazards.
Understanding the risk presented to buildings by bioterrorism has been a topic of research interest in recent years. Risk assessment methodologies and guidelines for the protection of buildings have been developed by a number of researchers, but it remains dificult to quantify the vulnerability and resilience of a building. It is an important issue from both biosecurity investment and operation point of view because different measures have different cost and operation implications. This paper reviews existing risk assessment methodologies, introduces a novel framework for classifying protection measures, and determines the inter-relation of the framework components and building vulnerability and resilience using a fault tree analysis within a biosecurity network system. Future work will develop weighting values for the different protection measures within the framework, allowing for the calculation of bioterrorism resilience of existing buildings, and to provide a decision making guide for building architects, builders, and managers for new and retroitted buildings.
