Experimental study on response of axially loaded steel and steel-concrete composite columns to blast loading

Original language description

Steel columns are often used thanks to ease of construction and high load-bearing capacity with limited overall dimensions. However, when exposed to extreme loads (blast, fire, vehicle impact etc.) steel cross sections are vulnerable and often need additional protection, which can be provided by encasing the section in concrete, effectively creating composite structure. The authors designed an experimental device to test columns subjected to simultaneous axial and blast loading. Steel-only columns and steel-concrete composite columns with normal strength concrete and ultra-high-performance fiber reinforced concrete infills were tested. Specimens were subjected to lateral contact blast while subjected to concurrent axial compressive load of varying magnitude simulating weight of a building with the aim of identifying influence of axial load on blast response. The response of the specimen was measured using photonic-doppler velocimetry (PDV) and evaluated. Blast damage reduction was observed with increased concrete strength. Beneficial effect of concurrent axial compression was also identified within reasonable axial loading magnitude. A direct link between blast damage to concrete infill and overall stiffness and blast performance of composite columns was observed as well. The use of high strength concrete showed its beneficial effects over normal strength concrete.
