Abstract:
Constructibility issues don’t always arise because members are heavily reinforced—geometry can also be a culprit. The intersections between a beam and a circular column or a curved wall are common examples. The curvilinear layout of the vertical bars in the column or wall results in slight offsets that can create “dead zones” through which horizontal bars cannot pass. Methods of dealing with these situations are discussed.
