| 摘要： | Operation DISTANT RUNNER produced data on the size and distribution of both airblast and debris produced by the detonation of 4500 kilograms of high explosive inside a Third Generation Hardened Aircraft Shelter. DISTANT RUNNER also produced data on the fragment/debris hazard ranges which are associated with detonations inside the shelter. After the full scale tests were completed, that event was modeled at two scales 1:10 and 1:4. These structures utilized detailed geometric modeling of both the rebar and the aggregate with which the reinforced structure was built. The concrete mixture, however, was modeled for the full-scale compressive strength. The 1:10 size model appeared to behave as if it were more like a 1:7 scale model. This appeared in the airblast, the size and distribution of the debris, and the hazard ranges produced by the debris. Because of this, testing at a larger scale was undertaken. This paper will present the results of breakup and debris throw for a quarter-scale shelter. Results obtained from all three scales will also be compared. For the structure modeled in these tests and with the decisions which were made about the details of the modeling utilized, the apparent scale factor (as determined from the breakup of the structure) differs from the design scale factor. As the scale size becomes larger (i.e., smaller models), the differences between design and apparent scale factor increases. |
