Discussion of the different design options available and the concept of ductility. ANCHOR DESIGN | ACI 318-14 UNIVERSITY AT BUFFALO Headed From the beginning of MecaStack (until v5532), the anchor bolt design was the same, which only checked the tensile capacity of the bolt. The document provides detailed calculations and concepts. Strength Design is state-of-the-art and Hilti recommends its use where applicable. Development Length ratio = 0.87: OK: 25.4.3.1: Overall: ratio = 1.21: NG Tension Also verified using Quick Anchor a software by S K Ghosh Associates. He is a member of the ASCE Task Committee on Anchor Rod Design, and an associate member of the Joint ACI- The new structural building code (ACI 2014) will be re-organized based on member type. A complete design for headed bolt anchors and its connection for different failure modes as per ACI 318-14 chapter 17. But unlike other chapters in the re-organized Code, Chapter 17 essentially remained an untouched clone of Appendix D. This was a conscientious decision by the 318 Code Committee at the beginning of the reorganization work, because: (1) the Appendix D anchor design provisions are still “relatively new” and (2) there was a desire to keep t… ACI 318-14 Section 17.2.3 has comprehensive instructions for seismic design, including considerations of brittle and ductile failures of the anchor systems. Simpson Strong-Tie® Anchor Designer™ is the latest anchorage design tool for structural engineers to satisfy the strength design provisions of ACI 318-14 Chapter 17 / ACI 318-11 Appendix D, CAN/ CSA A23.3 Annex D, ETAG 001 Annex C or EOTA TR029 design methodologies. The anchor, base material, base plate, and profile type/size can be found from the software output in Figure 2. Another difference between ACI 318-11/ACI 318-14 seismic shear anchoring provisions and ACI 318-08 seismic shear anchoring provisions is that anchorage design based on yielding of a ductile anchor element is not offered as a seismic shear option in either ACI 318-11 or ACI 318-14.
