Frontiers of Structural and Civil Engineering 2023, Volume 17, Issue 1,   Pages 138-151 doi: 10.1007/s11709-022-0897-y

Abstract: to the advancements in the field of concrete materials over the past few decades, concrete mixes of highcompressive strength, commonly referred to as high-strength concrete (HSC), have been developed.The finite-element model of a conventional normal-strength concrete (NSC) prototype wall was validatedThe HSC wall exhibited improved strength and stiffness, and thereby, allowed reduction in the longitudinalreinforcement area and size of the boundary elements for the same strength of the conventional wall.
