Building structure having high blast and penetration resistance

摘要

A building structure having high blast and penetration resistance, having a plurality of walls at least one of which is of a sandwich construction including four composite panel structures (CPS1 - CPS2) each including a first group of face panels (2) having interlocking ends, a second group of face panels (4) having interlocking ends spaced from said frist group, a plurality of laceing panels (6) extending diagonally between the two groups of face panels (2,4) and having ends interlocking with the interlocking ends of the two groups of face panels (2,4), and a filling material (8) filling the spaces between the two groups of face panels (2,4) and embedding the laceing panels (6). The filling material (8) filling the spaces between the face panels (2,4) is a solid material such as cast concrete and the space between the opposite panel structures is filled with a loose filling material (FM), such as loose sand, gravel, pebbles or stones.
