| Abstract |
Interest in the design and construction of structures to provide protection against explosive accidents or terrorist attacks has recently increased. In blast resistant design of buildings, the blast loading on structures is discussed and the response of structures or structural elements to blast loading is evaluated. In this paper, blast analyses of the selected H-shaped steel columns at the first story of steel frame structures were conducted using a sophisticated analytical approach or computational fluid dynamic finite element analysis method. The simulated blast pressure and impulse were first evaluated by comparison with the values from the calculation based on experimental data. The effects of the boundary conditions, such as beam-to-column connections and base plates, on the behavior and failure of columns under a blast loading scenario were observed through parametric studies of the simplified models and design requirements considered for the boundary conditions are suggested. |
