Numerical modeling of explosion of reinforced concrete magazine : effects of explosive configuration

The project is aimed to minimize the land required for the clearance zone measured from the hazardous sources such as explosive-storing magazine to ensure efficient uses of the land are being carried out in a land-scarce country like Singapore. The direction of this project study is aimed to explore...

description The project is aimed to minimize the land required for the clearance zone measured from the hazardous sources such as explosive-storing magazine to ensure efficient uses of the land are being carried out in a land-scarce country like Singapore.
