Peak Displacement Comparison of RC Slabs from Blast Test Measurement and SDOF Analysis Proceedings Article Mendonça, Fausto Batista; Urgessa, Girum; Iha, Koshun; Rocha, Roberta Jachura; Rocco, José Atílio Fritz Fidel Resumo | Links | BibTeX | Tags: blast effects, reinforced, single degree of freedom @inproceedings{Fausto2017blastb, Both civil and military facilities are increasingly targeted by terrorist attacks. Understanding the mechanical behavior of reinforced concrete (RC) structures subjected to blast is of paramount importance. A full-scale experimental program consisting of four reinforced concrete slabs with compressive strength of 60 MPa, measuring 1.0 x 1.0 x 0.08 m, and subjected to 2.7 kg of non-confined plastic bonded explosive, was conducted in blast test area of Science and Technology Aerospace Department (Brazilian Air Force). This paper presents theoretical peak displacement and compares with experimental displacement measured from the tests. Theoretical analysis was carried out using single degree of freedom (SDOF) models. The comparison showed that SDOF analysis worked very well in predicting the reinforced concrete slab peak displacement against blast effects. |
