ACI318

Version 3.0

  • Simpson mechanical anchor tested in accordance with AC355.2 and ICC-ES AC193 is added.
    • Titen-HD screw anchor in both cracked and uncracked concrete.
    • Titen-HD screw anchor in soffit of normal-weight and sand-lightweight concrete over metal deck.
  • New Simpson adhesive anchors tested in accordance with ICC-ES AC308 are added.
    • IXP anchor with SET-XP epoxy adhesive in both cracked and uncracked concrete.
    • SET-XP epoxy adhesive anchor with various steel inserts in both cracked and uncracked concrete.
  • Steel grade selection is added for cast-in-place heavy hex bolt and L-bolt. User now can select steel grade of either ASTM F1554 Grade 36, 55 or 105.
  • 7/8" diameter is added for heavy hex bolt and L-bolt.
  • Strong-Bolt installation in soffit of normal-weight and sand-lightweight concrete over metal deck is added.
  • Strong Bolt anchor category is updated from category 2 to 1 for 1/2" and 5/8" diameter anchors.
  • Updated to reflect latest information from Simpson Anchoring and Fastening Systems catalog, C-SAS-2008 (PDF to be released on this website in May 2008).
  • Updated help file.

Version 2.0.1.1

  • Updated 1/2" and 5/8" diameter Strong-Bolt Anchor Category from 2 to 1.
  • Shear breakout calculation is updated to limit parallel to edge strengths by twice the perpendicular to edge strengths, as applicable, as detailed in ACI Appendix D Section D.6.2.1(c).
  • Updated help file.

Version 2.0

  • Shear breakout calculation is updated to reflect the methodology in ACI 318 Appendix D Commentary Section RD.6.2.1.
  • Shear pryout calculation is updated to consider all anchors in the base plate regardless of applied tension loads at each anchor.
  • Installation of untorqued cast-in-place anchor near concrete edge is provided as an option.
  • Anchor embedment depths available at 0.25 inch increments.
  • Improved tool tip and user input interface.
  • Calculation output is updated to display an interaction equation and a summary sentence.
  • Updated help file.

Version 1.4

  • If Sand-Lightweight aggregate concrete is selected for post-installed anchors, all values of Nn and Vn affected by √f'c and Npn will be multiplied by 0.60. All-Lightweight aggregate concrete to be beyond the scope of the design provisions. (These requirements are based on ICC-ES AC193 and Simpson's assessment of available test data in Sand-Lightweight concrete.) For more information, read important information regarding ICC-ES's revised design recommendations for ACI 318 Appendix D (PDF).
  • Updated catalog page.

Version 1.3

  • Prevent user from selecting c,V < 1.4 for uncracked concrete.
  • The program retains more information when saving files.
  • Maximum anchor spacing used in concrete tension breakout calculation is limited to three times the effective anchor embedment for three edge condition.
  • Minor rounding error for cp,N corrected.
  • Limit f'c per ACI 318-05 Appendix D Section D.3.5 prior to applying adjustment factor for lightweight concrete per Section D.3.4.

Version 1.2

  • Concrete tension breakout area calculation has been revised when adjustment per ACI 318-05 Appendix D Section D.5.2.3 is applicable.

  • Concrete shear breakout area calculation has been revised for shear load applied in y-direction.

Version 1.1

At the input tab, the condition of the concrete is limited to being "cracked" when also considering seismic. Within the application, the calculation of the demand/capacity ratio for both tension-steel and tension-pullout have been modified.
