“…B. X. Qi1, S. Yan2, W. Li3 and X. J. Li. [12] H-shaped steel frame colu mn under a blast loading with different conditions was numerically developed, using finite element method (FEM) by considering the strain rate effect to materials and the coupled effect of exp losive, air, and steel together, to simulate t he response in the middle span, failure modes, shear strain responses at both ends of the colu mn. The t wo ends of the co lu mn were fixed and applied with a vertical load to simu late the responses of a bottom colu mn o f a steel frame structure under a blast loading by changing stand-off and the weight of the explosive, and the height of the colu mn.…”
