Abstract

In view of increasing threats of explosion from accidental and terrorists attack, the design of exterior column becomes critical as explosive load sometime exceed the design lateral seismic load. The columns which are vulnerable to explosive load are needed to strengthen in flexure and shear capacity. The closely spaced ties in the plastic hinge region confine the core concrete and resist the buckling of longitudinal reinforcement. Hence the adequacy of column reinforced according to IS 13920-2016 in resisting the blast load is numerically simulated in this study. The Fiber Reinforced Concrete (FRC) may enhance the shear and flexural resistance. The Long Carbon Fiber Reinforced Concrete (LCFRC) column for explosive loads is modeled in Finite Element (FE) software LS-DYNA. The result shows that the ductile detailed column resulted in improved shear resistance under blast load. The LCFRC columns results in reduced surface damage, cracking of concrete, and deflection. The column reinforced according to IS 13920-2016 and LCFRC column showed greater resistance to explosive load.
