We placed some No. 6 vertical bars at a slight incline in the first lift of a wall placement. The protruding dowels are now too close to the wall forms for the next lift. When the horizontal bars are placed, we have little allowance for movement of the forms and we can’t meet the clear cover tolerance. The contract documents permit cold bending of No. 6 bars, and we have approval from the Structural Engineer. We planned to bend the verticals with a hickey bar, but the Inspector told us we couldn’t create a bar slope greater than 1 in 6 when doing this. I’ve never heard of this rule and can’t find it in any ACI documents

The author describes significant changes to the provisions for anchors in concrete in the 2012 International Building Code (IBC). Prior to publication of the 2012 IBC, procedures for establishing the design strength of adhesive anchors in structural concrete did not exist in the code. Now, the 2012 IBC references ACI 318-11(“Building Code Requirements for Structural Concrete and Commentary” and ACI 355.4-10 (“Acceptance Criteria for Qualification of Post-Installed Adhesive Anchors in Concrete”) to provide the basis for the qualification and design of adhesive anchors

Appendix A of “Building Code Requirements for Structural Concrete (ACI 318-2011) and Commentary” provides requirements for design using strut-and-tie models, including provisions for the effective capacities of prismatic and nonprismatic (bottle-shaped) struts. The authors examine whether an increase in the width of a strut results in a reduction of its unit bearing strength. Based on their test results, the authors conclude that attributing a reduction in allowable compressive strength to the shape of a strut is an unnecessary rationalization
