Punching failure of reinforced concrete slabs subjected to hard missile impact:Part II, Recent tests and analyses on inclined impact
This paper considers two relatively recent tests with a hard oblique impact to a reinforced concrete slab, where only the impact angle of inclination is intentionally varied. The thickness of the reinforced concrete target slab is 250 mm and the span distance in both directions is 2 m. The targeted impact velocity in the oblique direction was 135 m/s. Test arrangement is described. Test results and corresponding Finite Element simulation results are presented and compared with each other. Structural behavior of the slab and the projectile were simulated reasonably accurately, although there are some different trends in the tests and simulations. In the tests, larger inclination angles led to lower residual velocities, but not as clearly as expected. In the simulations, however, the highest residual velocity was with the largest angle. The research of inclined impacts has just been started and the calculation models have to be improved for this new purpose. More tests of this type are also needed.
