| Summary: | As countries become more developed, more buildings and infrastructures will be built. Therefore, efficient use of land is important, especially for a land scarce country like Singapore. There are many factors to be considered when considering maximising usage of land. One of the factors is considering the required clearance zone measured from the hazardous source such as an explosive-storing magazine. In a land scarce country, national military defence is also important and is inevitable explosive-storing magazine has to be stored somewhere in the country. However, the safety of her surrounding citizens and buildings alike cannot be compromised in a bid to maximise land usage. Hence, this project aims to study the secondary trajectory of debris due to roll-and-bound motion from an accidental explosion of reinforced concrete magazine.
It will studied through two parts, with this report focusing on Part I which deals with intact concrete cube specimens and its effect of its geometrical shape, impact angle and its coefficient of restitution. Part I will also include determining a new criterion to differentiate the difference between a rebound and a ricochet phenomenon.
The project will be continued onto Part II which it will deal with damaged concrete cube specimens of the same shape and size and soil conditions. The details of Part II can be found in her partner Choo Kay Wei report (K.W.Choo, 2013). Part II will focus on the stochastic dispersion break up pattern of the concrete debris when it strikes a soil medium. |
