It is an ideal tool for doing quick iterations for design purposes as well as computing the design strength of existing anchor(s). Example of Concrete Anchor Bolt Design Calculation – Part-1: Determining Steel Strength of Anchor Bolt in Tension. For example, using ACI 318-77, Vt = 1.4Z) + 1.7L Tp — Tension design load effect equal to the product of the load factor(s) and the nominal tension load. This site uses Akismet to reduce spam. In this part we will calculate the side-face blowout strength of the concrete anchor according to the ACI 318 Appendix D codes and also consolidate the results of the different types of anchor strengths in tension we have calculated so far. Side-face blowout strength 4. When the anchor bolt is too close to the side then the possibilities are there that before breaking out the top concrete surface, the side surface get broken. In previous editions of ACI 349, the anchorage design was given in Appendix B. Breakout strength, 2. So, from equation 4.1, 0.4**hef is 4 which is less than Ca1 so we need to calculate side-face blowout strength for this example. 2015 IBC Chapter 19 seismic anchoring provisions reference ACI 318-14 Chapter 17 seismic anchoring provisions.
