![]() Test reports shall be available on request to the approved agency, design professional and enforcement agency. Reinforcing steel specimens containing the holding wire shall be tested for yield and tensile strength at the frequency required by Section 1910.2. Quality control tests shall be performed on shop welded specimens by the fabricator. Holding wire weld locations shall not occur on any longitudinal or primary reinforcing nor on any portion of a reinforcing bar that is or will be bent in accordance with ACI 318 Section 25.3 for the extents specified in AWS D1.4 Section 4.2.6. Tack welding of primary reinforcing bars together or to stirrups/ties is not permitted. Subject to prior approval of the enforcing agency, longitudinal holding wires conforming to ASTM A1064, of maximum wire size W5, that are machine resistance welded to stirrup/tie cage (or spiral assemblies) consisting of low alloy steel reinforcing conforming to ASTM A706 are permitted when performed under continuous competent control in a fabrication shop. Modify ACI 318 Section 26.6.4.1(b) by adding the following: Testing is not required for power actuated fasteners used to attach tracks of interior non- shear wall partitions for shear only, where there are at least three fasteners per segment of track.Testing of shear dowels across cold joints in slabs on grade, where the slab is not part of the lateral force-resisting system shall not be required.The dowels are uniformly distributed across seismic force resisting members (such as shear walls, collectors, and diaphragms).Īnchors to be tested shall be selected at random by the special inspector/inspector of record (IOR). ![]() The number of dowels in any one member equals or exceeds twelve (12).The dowels are used exclusively to transmit shear forces across joints between existing and new concrete.Where adhesive anchor systems are used to install reinforcing dowel bars in hardened concrete, only 25 percent of the dowels shall be tested if all of the following conditions are met:.Where the design tension on anchors is less than 100 pounds and those anchors are clearly noted on the approved construction documents, only 10 percent of those anchors shall be tested.Undercut anchors that allow visual confirmation of full set shall not require testing.just some general knowledge (which I have discovered isn't so general!). So I wasn't fishing for "free engineering". The closer I can get to a "correct" design and call-out the least amount of time and effort it'll take the experts to change. My question here is for my own education, the work I've done is already out the door (where I used the 30x dia.s). And I'm sure you'll agree it's easier to change something that is existing rather then start something from scratch. I take my best shot at it, BUT I point out to my bosses that my work needs to be checked by someone that KNOWS WHAT THEY ARE DOING!!!. material procurement, estimating, Xerox machine repair, AND civil and structural design. I now work for a small engineering firm where I'm pressed to cover other bases. BUT I'm better then a "monkey see monkey do draftsman". Now I'm the first one to point out I am not expert in these other disciplines!. During that time I've had to "bump" up against other disciplines and got to get a "feel" for what they do and how. To explain, my discipline is process piping.
