    Minimum Flexural Reinforcement ACI 318-19 8.6.1.1 for a very thick slab

    I have a foundation slab that is 4'-11 thick (the total dimensions are 14 ft x 14 ft x 4'-11" thick) & I am wondering if Minimum Flexural Reinforcement ACI 318-19 8.6.1.1 is applicable to this foundation. The applied vertical force is 100 kips & an applied moment of 295 k-ft. This is an...

    Using Bond Breaker vs Sleeve for Anchor Bolts to address Ductility

    What is the proper way the bond breaker tap should be sufficiently & properly wrapped around the anchor bolt? Is there any technical documents that provide commentary on this?

    Using Bond Breaker vs Sleeve for Anchor Bolts to address Ductility

    If a template is being used to place the anchor bolts for the vertical vessel, would that take care of the alignment of anchors required during installation equipment?

    Using Bond Breaker vs Sleeve for Anchor Bolts to address Ductility

    In PIP STE05121 Application of ASCE Anchorage Design for Petrochemical Facilities it says the following: “In the case of larger diameter anchors, the only relevant applications for using a sleeve are to provide stretch length to meet the requirements for the anchor to be a ductile steel...

    TORNADIC Wind Loads using ASCE 7-16

    I have a project located in Clarksville, Tennessee & I have been asked about consideration for Tornadic Loads. I used the ASCE Hazard Tool (https://ascehazardtool.org/) to determine if TORNADIC Loads shall be considered for Clarksville, Tennessee. Based on the ASCE Hazard Tool, it seems that...

    ACI 318-19 Section 17.10 - 17.10.5.3a

    So then is 17.10.5.3a (iii.) essentially just asking to confirm that the stretch length for the anchors meets the 8da requirement?

    ACI 318-19 Section 17.10 - 17.10.5.3a

    Thank you for the explanation. I am still not clear on (iii). It seems like the code is asking for one to do a check for the anchor bolt while using an additional ductile steel element to help resist tensile loads: (iii) Anchors shall transmit tensile loads via a ductile steel element with a...

    ACI 318-19 Section 17.10 - 17.10.5.3a

    I am looking at 17.10.5.3a & I had some questions about iii., iv., & v. Could someone provide some insight about these subsections of 17.10.5.3a? It seems to me that 17.10.5.3a part vi. is referring to using the adjacent vertical rebar to help resist the tensile forces. Could anyone please...

    ACI 318-19 Section 17.10 - Anchor Bolt Design for Seismic Site Class C

    What would you consider a "ductile steel anchor" regarding 17.10.5.3a(iii.)? R17.10.5.3 refers to these items as ductile steel elements.

    Thank you for this information. Do you happen to have a sample calculation of this process?

    ACI 318-19 Section 17.10 - Anchor Bolt Design for Seismic Site Class C

    I am working to get Hilti Profis, but in the meantime seeking a reference calculation. Does any one know if Guide for Design of Anchorage to Concrete: Examples Using ACI 318 Appendix D has been created based on ACI 318-14? I am basically trying to see if there is a more recent edition to ACI...
