Structural Response With Regard to Explosions

TL;DRAbstract

When a structure is subjected to an explosion, it will have a response that differs from the one that arises from a static load. Engineers are used to design for static loads but the common knowledge of how to design for explosions is weak. There are guidelines for how to design for explosions with simplified methods but they are partly outdated and the explanation of how they are derived is vague. This Master thesis compiles some of the most important guidelines and explains the underlying theory. In order to understand the structural response one must first study basic theory of explosions, different material behaviours and basic dynamics, which are also presented in the thesis. A structure can be simplified by transformation into a single degree of freedomsystem(SDOF-system), and the reliability of such an SDOF-system is evaluated within this thesis. The SDOF-system is created by using a system point where the maximum displacement will occur, and it is compared to hand calculations
