Analysis for FRP strenghtened RC walls subjected to blast loading

Presently, the need to increase the resistance of existing structures against blasts had increased, especially for those not designed to resist any explosion. This is because of the rising threat of terrorists’ attacks or sabotage, making them very vulnerable. Thus, more experimental and finite elem...
