High-Strength Concrete Cylinders Subjected To Axial Impact

By Motaz Elfahal

Abstract

Structural concrete can be subjected to high loading rates, such as those associated with impact and explosion incidents. It was found that the specimen size of regular strength concrete (RSC) subjected to static loading influences its behavior. This phenomenon is known as "Size Effect." However, no information is available on the effect of higher loading rates, or on the influence of high strength concrete (HSC) on the size effect. A numerical and experimental study was carried out on geometrically similar high strength concrete cylinders of different sizes subjected to axial impact in an attempt to investigate the size effect phenomenon for high strength concrete under impact loads.
