| Abstract: | The concrete infilled rectangular steel tube(CIRST) column is a kind of typical member used in light-weight steel frame structures.The explosion happening in the building due to the gas leaking may cause severe damage to the CIRST columns.However,less attention was paid to the enormous damage to the column under the blast loading.A typical CIRST column is numerically analyzed in the paper to investigate the dynamic responses and failure modes under the blast loading by using finite element software ANSYS/LS... |
