Concrete walls: The evaluation of the reinforcement design methods in D-regions around openings and overhangs

Unlike for concrete beams and plates, relative little amount of theory is present for concrete walls. In combination with the underexposure of the reinforcement design of D-regions in the codes when concrete walls are considered, engineering companies struggle to find a clear reinforcement design procedure which is agreed upon by all relevant parties. This report will therefore focus on the reinforcement design of D-regions around openings and overhangs for concrete walls loaded by a high distributed load. The goal of this report is to clarify whether both design methods are good methods for the reinforcement design of the cases considered. Furthermore the weaknesses of both methods are indicated and recommendations are given on how to improve the designs.
