Feasibility study on a cumulative damage assessment method for a reinforced concrete slab under blast loads
Seung-Hun, Sung
Agency for Defense Development, South Korea
T
his study proposes a novel cumulative damage assessment method for a reinforced concrete (RC) slab using an equivalent
single degree of freedom (SDOF) model. The proposed method utilizes a structural permanent deformation evaluted from the
equivalent SDOF model and its newly constructed resistance function due to initial damage. In order to confirm an applicability and a
limitation of the proposed method, a series of numerical simulations and experiments were carreid out. Three consecutive explosions
were numerically and experimentally conducted at same detonation points with the same explosive weight for the one-way RC slab
and for the two-way RC slab. As a result of comparison between numerical simulaions and experiments, it is sufficiently applicable
to assess cumulative damages for a RC slab under blast loads, although the method has some limitation.
