Fifteen static and dynamic tests were conducted to measure the actual magnitude of the curvature of a plastic hinge and to correlate the angle of deformation with resistance for beams subjected to dynamic loads. The primary variables were the amount of compression reinforcement, the distance between the concentrated loads, and the rate of loading. The dynamic step loads ranged in magnitude from about 1.10 to 1.25 times the static yield load. The computed values of moment, curvature, and deflection at the onset of plastic hinging were less than the experimental values for both static and dynamic loadings. The 30% increase in beam resistance under dynamic loads agreed with the increase in yield strength of the coupon specimens subjected to rapid straining. Plastic hinging was similar in the static and dynamic beams loaded at mid-span. Crushing occurred at approximately the same deflection under both types of load. For the beams with a pure moment region, a dynamic load equal to approximately 1.1 times the static load caused crushing at mid-span before the plastic hinge had developed as completely as it did for static loading; thus, for dynamic loads, the deflections were lower at the onset of crushing than they were for static loads.

Although much research focuses on investigating the responses of reinforced concrete (RC) structures under sole impact or blast loads, the responses of RC structures under a combination of impact and blast loads currently represent a gap in our knowledge. The combined actions of impact and blast loadings may be applied to RC structures during accidental or intentional collision of vessels, vehicles, etc., carrying explosive materials. A comprehensive study on the vulnerability of various structural members is carried out using finite element (FE) simulations under combination of impact and blast loads with the variations of various loading- and structural-related parameters and key parameters. This book introduces various structural analysis approaches for concrete structures when subjected to extreme loads such as impact and blast loadings. The theory of the combinations of impact and blast loads is proposed that can provide primary insights to the specific readers to develop new ideas in impact and blast engineering, including combined actions of extreme loads arising from real-world intentional or accidental events. This book will be of value to students (undergraduate or postgraduate), engineers, and researchers in structural and civil engineering, and specifically, those who are studying and investigating the performances of concrete structures under extreme loads.
