<br />For SI: 1 inch = 25.4 mm. 1 Ibf = 4.45 N. 1 psi = 0.006895 MPa For pound -inch units: 1 mm = 0.03937 inches.
<br />Figure 2 of this report illustrates the installation parameters.
<br />' The KB-TZ2 is considered a ductile steel element in accordance with ACI 318-19 2.3.
<br />The strength reduction 'actor applies when the load combinations from the IBC or ACI 318 are used and the requirements of ACI 318-19 17.5.3 are met The strength
<br />reduction factors are applicable with supplementary reinforcement is not present. Greater strength reduction factors may be used in areas where supplementary
<br />reinforcement can be verified.
<br />' For all design cases, W, = 1.0. The appropriate effectiveness factor for cracked concrete (kc) or uncracked concrete (k, _) must be used.
<br />s For all design cases, W:,v = 1.0. Tabular value for pullout strength is for a concrete compressive strength of 2,500 psi (17.2 MPa). Pullout strength for concrete
<br />compressive strength greater than 2,500 psi (17.2 MPa) may be increased by multiplying the tabular pullout strength by (Pc / 2,500)" for psi, or (fc / 17.2)" for MPa,
<br />where n is given as n,- for uncracked concrete and n , for cracked concrete NA (not applicable) denotes that pullout strength does not need to be considered for
<br />design.
<br />' For core drill installations, K_ = 24 and k„ = 17 for'/4-inch diameter anchors installed at 31/4 inches (95 mm) effective embedment.
<br />For core drill installations, N,,, = 4245 lb (18.9 kN) and N,. = 42451b (18.9 kN) for '/rinch diameter anchors installed at 3'/, inches (83 mm) effective embedment.
<br />"/,-inch and 1-Inch diameter anchors are not permitted for core drilling installations.
