In report D4, the mass runs covered CFRP strengthened RC walls. In this report D5, as a supplement, some additional cases of CFRP strengthened RC walls by uncased charge have also been studied for ANN analysis. Moreover, additional cases of CFRP strengthened RC walls using the large cased charge, denote as “device B”, have been studied. Nevertheless, in report D5, mass runs are mainly devoted to GFRP strengthened RC walls subject to near-field blast effects and fragment loading. The tensile strength of GFRP has been re-tested and used in the mass run. Some cases of un-strengthened RC walls subject to near-field blast effects and fragment loading have also been studied, to establish a reference to literature limit curves which thus serves as additional validation. With a new GFRP test is available, the validation simulation has been carried out. The bigger size RC wall with CFRP\GFRP by Device B has been studied. Finally, the engineering tools have been developed and the guidelines have been provided.
