<br />1 Design information is taken from ICC-ES ESR-4236, dated July 2018, table 2, and converted for use with CSA A23.3 Annex D.
<br />2 The HDI-P TZ is considered a brittle steel element as defined by CSA A23.3 Annex D Section D.2.
<br />3 All values of R are applicable with the load combinations of CSA A23.3 Chapter 8. For concrete failure modes, no increase for Condition A is permitted.
<br />4 N,,,= N„ yt, R,," where N„ tabular value above is preoalculated from A,.,, f..
<br />5 For all design cases, Wua =1.0. The appropriate effectiveness factor for cracked concrete (k,,,) or uncracked concrete (k,,,,) must be used.
<br />6 For all design cases, y., =1.0. Tabular value for pullout resistance is for a concrete compressive strength of 20 MPa (2,900 psi). Pullout resistance for
<br />concrete compressive strength greater than 20 MPa (2,900 psi) may be increased by multiplying the tabular pullout resistance by (A,/20)°-for MPa or
<br />(f, / 2,900)69fi for psi. NA (not applicable) denotes that pullout strength does not need to be considered for design.
<br />7 Shear and seismic shear tests are all performed in cracked concrete member per ICC-ES AC193 section 9.4 and 9.6 respectively. Value of V,° < 0.6 A,,,v fN
<br />for all cases. Multiply V. tabular value above by yt, R,,v to get V,,, and V.,.,,.
