| Abstract | ||||
| Research on the effects of blast loads on concrete structures has been conducted extensively in recent decades. This is primarily due to the increasing risk of deliberate explosive attacks, accidental explosions, and other types of explosion-related failures that structures worldwide are facing. The magnitude of blast loads generated by most explosions far exceeds the design loads considered in traditional structural design. Consequently, this heightened awareness has prompted building owners, government agencies, and design professionals to prioritize the ability of buildings to withstand blast loading and ensure the survival of structures in the face of constant global terrorist attacks. This research paper focuses on the modeling and dynamic analysis of the foundation of a steam turbine generator, which is an important and valuable element. While there have been previous studies on the behavior of reinforced concrete (RC) structures under blast loads, this paper specifically examines the nonlinear dynamic responses and failure behaviors of the supporting structure of turbine generators subjected to blast loads using Explicit Dynamic Analysis in Ansys Workbench. The study investigates the effects of middle-rate impact loading stresses on the blast responses of RC structures. By conducting dynamic analysis using Ansys Workbench, the researchers found that the RC structure is significantly influenced by the blast load. Moreover, they observed that the effect of the blast load decreases as the distance between the TNT source and the RC structure increases. | ||||
