• strain rate effect
• yielding delay time
• air-blast loading
• reinforced concrete structure

A new method to calculate the dynamic strength of reinforced concrete (RC) structures, with emphasis on the embedded response of mild steel reinforcement, subjected to air-blast loading is derived. The proposed method is based on a singledegree-of-freedom (SDOF) system with appropriate modification for strain-rate effect. Approximate formulae are used and explained in detail. A numerical example is presented to show how the derived formulae are used for the analysis of concrete structures subjected to air-blast loading.
