Numerical Prediction of Cantilevered Reinforced Concrete Wall Subjected to Blast Load

Aggressor attack using improvised explosive not the only source for blast load. Some commercial equipment and daily activities can contribute as well, such as electrical transformers, gas pipelines and industrial plants. Normally, reinforced concrete wall is used as the protection. Therefore, it is...
