Evaluation of the (UHP)FRC slab contact blast resistance with numerical simulation using LS-DYNA
Original language description
Recent development of a security situation in the world and rising numbers of bomb attacks raised new requirements on the material properties and its resistance against blast loads. Commonly used concrete mixtures do not sufficiently meet these requirements. To describe concrete blast resistence and improve it, series of the experiments with full scale specimens were performed. Various concrete specimens made of usually used FRC up to less used UHPFRC were loaded by contact blast. Different concrete mixture attributes as strength, fracture energy or amount of fibres in the specimen and its influence on the blast resistance were evaluated. Results show positive effects of the increased compressive strength and fracture energy on the blast resistance. However, results indicate that blast resitance of the composite slab can be influenced in relatively easier and cheaper manner than by reaching high compressive strength and flexure energy values.
