A Protective Structure, Saver During Structural Collapse

In this paper a new protective structure is presented to save human life, in the case of building collapse, caused by an earthquake, a terrorist attack or other catastrophic events. The life-saver device discussed here is a bolted-moment-resisting 3-D steel frame that encapsulates a single or double-bed sleeping area at home. The frame consists of a number of beam-columns of angle cross-section, bolted together by gusset plates and topped with a thin steel plate or a rectangular rebar mesh. Austenitic twinning induced plasticity (TWIP) steel which has a good combination of both strength and ductility also has been used for modeling and designing this structure and the results has been compared with ordinary steels. The design is verified for the emergency limit state considering the safety of people inside the protective structure.
