Abstract |
Prestressed concrete is widely utilized for the construction of various structures such as bridges, buildings, and nuclear facilities. However, studies of impact resistance on prestressed concrete members are still lacking, and there is no applicable design equation in particular. In this study, impact test data of the prestressed concrete panel tests performed by other researchers were analyzed to assess the effect of prestressing force in a concrete panel, and nonlinear finite element analyses were performed for parametric study. Based on this, a new empirical equation was proposed in order to predict the ballistic limits of bonded prestressed concrete panel. The proposed equation was verified with the use of test data and analytical studies. As a result, it is expected to be effectively used for the design of prestressed concrete structures.
