In order to study the kinetic energy weapon damage effect to concrete targets, based on the experiment and numerical simulation method,the tungsten alloy projectile hyperve-locity impacting concrete building structure was studied and concrete building structure damage characteristics were discussed under the condition of hypervelocity impact.The weight of tung-sten alloy projectile used in the test is 35g,the ratio of which length to diameter is 5,and which impact velocity is 2.5km/s;the concrete compressive strength of building structures target is 34.4MPa.Studies had found that the top plate and bottom plate of the structure target were pen-etrated without the occurrence of disintegration under the experimental conditions.In addition, reinforcement in the target body had no significant effect on the test results.Calculated and ex-perimental results showed that speed of projectile fell from 2.5km/s to 2.0km/s~2.3km/s after impacting 40mm concrete slab.The debris cloud from concrete structure top plate had considera-ble speed.Some of them had strong killing effect on the staff with 23°expansion angle,while distribution range was greater than the perforation diameter on the bottom plate.
