<br /> 1.The designer shall specify the foundation anchor material type,embedment and configuration. 1
<br /> 2.Stud design by specifier.Tabulated loads are based on a minimum stud thickness for fastener connection. 1
<br /> 3.Deflection at ASD or LRFD includes fastener slip,holdown deformation and anchor rod elongation for hoidowns installed ,
<br /> up to 4°above top of concrete.Hoidowns may be installed raised,up to 18'above top of concrete,with no load reduction I
<br /> provided that additional elongation of the anchor rod is accounted for.See bottom of p.169 for installation detail.
<br /> 4.The Nominal Tension Load is based on the tested average ultimate(peak)load and is provided for design in accordance
<br /> with section C5 of AISI S213 that requires a tension tie to have a nominal strength to resist the lesser of the amplified I
<br /> seismic load or the maximum force the system can deliver. i
<br /> 5.See Fastening Systems catalog(C-F-2019)on strongtie.com for more information on Simpson Strong-Tie fasteners.
