A METHODOLOGY FOR STRUCTURAL ANDCOMPONENT DAMAGE ASSESSMENTOF BUILDING TARGETS

摘要

One of targets of increasing significance in recent operations is building. The JointMunitions Effectiveness Manual (JMEM) approaches for evaluating structural damage tobuildings use the Building Mean Area of Effectiveness MAEBLDG (in square meters in theground plane) as the Effectiveness Index (EI). MAEBLDG, the numerical values areclassified, is used to describe the damage function for building and is area over which aweapon will damage the building. With this MAEBLDG values, the building damage isestimated for specific the building dimensions and weapon delivery accuracy [1].In general the warhead detonates external to the building in air or after penetrating theroof, walls and floor slabs. It is inadequate to use the fixed MAEBLDG values for thespecific building types since the MAEBLDG varies as the detonation location at thebuilding target. Target elements inside buildings are usually personnel or equipment. Inmany cases, it is only required to kill the function or activity performed inside thebuilding rather than destroy the building itself. Therefore the damage should beconsidered in two ways:1) structural damage and 2) functional damage.This paper deals with the methodologies to estimate both structural damages ofbuildings caused by detonations insides or outside the structures without usingMAEBLDG concept. This method uses the specific weapon-structure interactions and MonteCarlo to capture the delivery accuracy of the weapon.
