Preliminary findings from experimental study on blast performance of steel-concrete composite columns

Popis výsledku v původním jazyce

The use of steel-concrete composites in blast resistance has gained importance in the recent years, since concrete is not able to resist higher explosive charges. The authors have designed an experimental device to test steel-concrete composite columns subjected simultaneously to axial and blast loading. The experimental device in a shape of a closed steel frame allows to test plain steel columns, composite steel-concrete columns and composite steel-using ultra-high performance fiber-concrete (UHPFRC) columns. The specimen is loaded with 800f of explosive charge while subjected to axial compressive loading. The response of the specimen is acquired using photonic-doppler velocimetry (PDV). The paper presents preliminary results from the first run of the experiment documenting the benefits of composite action on blast resistance of the tested columns. The use of UHPFRC also showed its beneficial effects. This paper presents preliminary findings from the experimental program.
