This is mainly due to the fact that structures all over the world are increasingly being exposed to the threat of premeditated explosive attacks, accidental explosions and other forms of explosion related failures. The magnitude of blast loads produced by most explosions are significantly higher than the design loads for conventional structural design. Consequently, this has increased awareness of building owners, government departments as well as design professionals to the vulnerabilities and survivability of structures to blast loading as global terrorist attacks continue at an increasing rate. The finite element modeling and dynamic analysis of massive and elevated foundation of steam turbine generator is considered in this paper. Despite many studies existing in the literature on the investigation of reinforced concrete (RC) structures under blast loads separately, this paper numerically evaluates the nonlinear dynamic responses and failure behaviors of turbine generators supporting structure subjected to blast loads using Explicit Dynamic Analysis-Ansys Workbench. The effects of the middle-rate impact loading stresses on the blast responses of RC structures are studied. The results of dynamic analysis by Ansys Workbench showed that the RC Structure is greatly affected by the explosive load whenever the effect of blast load decreases by increasing the distance between the source of TNT and RC structure.
