Blast resistant design and limits of the response of a structure to an external explosion

摘要

A 3-D dynamic analysis of an entire structure is used to determine the effects of an explosion and the response of a structure. Damage to the structure is assessed accordingly, firstly by the angle of rotation of the middle axis/surface, and secondly by the limit internal forces of the selected structure. The extreme nature of blast resistance makes it necessary to accept that structural members have some degree of inelastic response in most cases. This enables the application of structure dissipation using the ductility factor. The limits are correlated with qualitative damage expectations. The methodology for dynamic response assessment and its application to the new RC building is discussed.
