In-Structure Shock of Surface Structures: A Theoretical Approach

الملخص EN

Metal foam cladding emerges as a promising measure for structure protection against close range blast.

With proper cladding design, a considerable amount of energy can be absorbed while the load transmitted to the protected structure can be lowered to a controllable level, leading to less damage of the protected structure.

However, it is not clear whether the in-structure shock can be mitigated by attaching foam cladding.

The present study theoretically investigates the response of a structural member subjected to a close range blast, for both scenarios with and without attaching foam cladding.

Subsequently, shock response spectra are employed to assess the in-structure shock of both situations.

It is found that applying foam cladding does not effectively mitigate in-structure shock of surface structures.
