Structure Analysis Loaded by Interior Blast Effect

摘要

The paper determines the parameters of the explosion wave excited by a terrorist charge and assumption of the building structure of a railway station based on dynamic analysis. Certain simplified methods according to various publications, according to our own experimental results and according to 3D computations based on detailed calculation modelling of the interior of the room are compared to determine the explosive effects. Equivalent static analysis was applied to the dynamic response of the structural elements of the selected room. The damage caused to these structural elements is weighted on the basis of the angle of failure of the central axis/surface, and on the basis of the limit stress state of these structures.
