<br />54.7.3 Ultimate Load Capacities for Installations Using Reinforcing Bars in Conc.rete
<br />
<br />The following load capacities are the ultimate or failure load for the Power-Bond adhesive based on tests using Grade
<br />60 reinforcing bars. The steel strength values are based on the minimum strengths as listed in ASTM Standard A 615.
<br />Actual results may vary depending upon the base material condition and reinforcing bar tolerance.

<br />54.7.4 A!lowilble Load Capacities for Installations Using Reinforcing Bars Rod in Concrete
<br />
<br />The values for the bond strength in tension are based on applying a safety factor of four to the ultimate capacities listed
<br />in the previous section. The values for the bond strength in shear are based on applying a safety factor of four to the
<br />ultimate shear load capacities for the tests conducted with high strength threaded rod. The tension loads for reinforcing
<br />bars are based on the allowable stresses as listed in Section 1926.3.2 of the Uniform Building Code. The shear loads for
<br />reinforcing bars are based on the allowable stresses listed in Section 1926.7.6 and 1911.7.4. The shear-friction coefficient
<br />based on section 1911.7.4.3 for normal weight concrete was 0.6. The allowable shear load is based on applying the
<br />allowable shear stress to the cross sectional area of the bar and then factoring by the shear-friction coefficient. The
<br />allowable load should be the lesser of the bond strength or the steel strength.
