摘要：

A numerical model of the reinforced concrete (RC) columns was developed using software LS-DYNA.In the numerical model, the smooth particle hydrodynamics (SPH) method is used, and the spalling effect and strain rate effect are considered. The finite element model is valiated through the experimental data. A parametric study is further carried out to examine the effects of ultra-high performance concrete(UHPC), high strength concrete(HSC) and high strength steel(HSS) on the blast resistance of RC columns. The results show that, compared with normal strength concrete column (30 MPa compressive resistance) and high strength concrete column(80 MPa compressive resistance), the blast resistance of UHPC column (140 MPa compressive resistance) is increased by ten times under same scaled distance of 0.8 m/kg1/3. However, HSS results in more brittle damage in UHPC columns. The damage mode of RC columns changes from flexure to shear. © 2021, Editorial Board of Acta Armamentarii. All right reserved.
