Response of reinforced SIFCON-slabs under blast-loading Chr. Mayrhofer Fraunhofer-Institut fur Kurzzeitdynamik, ERNST-MACH-Institut Institutsteil Wintersweiler, D-79588 Efringen-Kirchen, Germany ABSTRACT The response of ,,reinforced SIFCON"-slabs under static and dynamic loading conditions was experimentally investigated. The bending capacity was deter- mined and iso-damage curves in p-J-diagrams were calculated. The bending capacity as well as the energy absorption capacity proved to be much higher compared to normally reinforced concrete. The increasing brittle behaviour of reinforced concrete slabs with increasing reinforcement was not observed with reinforced SIFCON. As a result reinforced SIFCON can be used favorably to design highly dynamically loaded structures. INTRODUCTION To improve the response of structures to highly dynamic loading it is important to use a material with large working capacity. SIFCON (Slurry Infiltrated Fibre Concrete) has high tough
