摘要

The design of explosive processing facilities for Department of Defense (DoD), Department of Energy (DOE), other government organizations and government contractors has been primarily governed by the November 1990 version of TM5-1300 for almost two decades since its publication. The document contains prescriptive and recommended design procedures for the design of structures to resist the effects of accidental explosions. The procedures were developed from explosive testing-- extensive in some areas, but very limited in others-- and good engineering practice. Since the publication of TM5-1300, the state of the art methods in computational fluid dynamics and structural analysis have improved tremendously in their ability to more accurately predict the response of structural components to blast loading. This has been verified and validated through many government-sponsored test programs. These test programs have also improved the accuracy of empirical and simplified engineering tools to predict the response of structural components to blast loading. Due to the prescriptive nature of TM5-1300, this body of knowledge is generally not available for use in design. Blast testing of systems is often required to demonstrate their ability to meet the intent of the standard when they fall short of meeting the strict prescriptive requirements of TM5-1300. The testing is not only very costly, but also time consuming which may prevent users from meeting aggressive design and construction schedules. Therefore, most engineering projects conform to the prescriptive requirements of the TM5-1300 standards. In this manner, the design can be reviewed through conventional government channels and delays caused by the testing process are avoided.
