Abstract
The explosion accidents and terrorist attacks in the structures are directly connected to the horrible disaster. Particularly, the collapse of the structure caused by the explosive accidents has caused many casualties. Therefore, it is necessary to establish the technology to predict and prevent the damage of the structure due to the explosion load. In this study, the behavior of slab-column joint subjected to explosive load was analyzed. In order to evaluate the behavior of structures, the structure including interior columns, edge columns, and corner columns was modeled. The behavior of each slab-column type was analyzed according to the location of the explosive load, which is the main analytical variable. The analysis results include the deflections of the member, the stresses of the reinforcements, and so on.
Keywords: Concrete, Structures, Slab-column Joints, Blast Loads
