DEFINITIONS OF STRESS DISTRIBUTION / YIELD ZONE FOR CONCRETE BARRIERS

The literature presents the research results of a§three-dimensional analysis of a concrete barrier and§anchor slab on a reinforced soil (MSE) retaining wall§system under AASHTO impact test loading. It has the§potential to assist practicing engineers and§researchers in understanding the characterization of§a concrete barrier, anchor slab, and reinforced soil§retaining wall assembly under an impact load §condition. §§This literature investigates the stresses on the§concrete barrier with anchor slab, as well as stress§distribution on the concrete barrier that is under§impact loads specified by the AASHTO code. A§discussion of the pattern of the potential yield zone§on concrete barrier is included in this literature.§Few research models are established to compare the§yield zones and stress distributions. Based on§research results, this literature questions the yield§line theory defined by AASHTO. It could potentially§allow practicing engineers to understand the design§concept of the yield line defined by AASHTO and§produce new topics for future research.
