Bundling of headed bars in concrete

The present note presents tests of specimens reinforced with short headed bars (studs) with head area equal to ten times the bar area. The yield strength of the stud is developed solely by the head; thus, the stud can be plain (non-deformed). The objective of the tests is to show that up to four hea...

Zusammenfassung:	The present note presents tests of specimens reinforced with short headed bars (studs) with head area equal to ten times the bar area. The yield strength of the stud is developed solely by the head; thus, the stud can be plain (non-deformed). The objective of the tests is to show that up to four headed bars can be grouped in a bundle to act as a unit, and to recommend rules for detailing.
