Effect of Blast Loading on Seismically Detailed RC Columns and Buildings

Explosions caused by standoff charges near buildings have drastic effects on the internal and external structural elements which can cause loss of life fatal injuries in case failure or collapse element. Providing with blast resistance is therefore gaining increasing importance. This paper presents numerical investigation RC columns different reinforcement detailing subjected to near-field explosions. Detailed finite element models are made using LS-DYNA software package for several having seismic conventional were previously tested under loads. The results show agreement published experimental regarding displacements damage pattern. Seismic enhances shape column decrease displacement values compared detailing. Further, effect modeling parameters studied such as mesh sensitivity analysis, inclusion air medium erosion that decreasing size, value region provide very close results. Additionally, application a slab-column multistory building provided protective walls connection details this study presented discussed. Use top bottom floor slab better than full at four sides adjacent slabs. leads minimizing distortion column, it increases chance saving from human lives. Doi: 10.28991/cej-2021-03091733 Full Text: PDF
