Title: Proposed Revision of Building Code Requirements for Reinforced Concrete (ACI 318-47)
Author(s): ACI Committee 318
Publication: Journal Proceedings
Appears on pages(s): 269-275
Keywords: no keywords
Abstract:Proposed changes decrease the allowable bond stress in plain bars (including the old types of deformed bars) and increase the allowable bond stresses for the new types of bars over those previously for the old types. Top bars, those having more than 12 in. of concrete under them, are assigned lower bond stresses than bars in other positions. All plain bars must be hooked, which coresponds to special anchorage under the old provisions. The new bars develop sufficient anchorage by bond alone to correspond to special anchorage with the old type bars. Consequently, all the bars under the new provisions correspond to those with special anchorage under the old provisions.
