Subject: Retail Structural Wall
Question: During investigation of the retail wall that currently divides the retail from admin offices,it was discovered the wall is structural and upgrades to the wall
will be necessary in order to open the wall as defined on A2.1.
Please advise what modifications will be necessary.Preliminary definition has been provided and further research is being investigated.Using the RFI
system to document and not lose sight of item in the works.
Thank you.

1. The entire pointed portion of the fastener must penetrate through the steel to obtain the tabulated values,unless otherwise indicated.
2. The allowable shear values are for the fastener only.Members connected to the steel must be investigated separately
in accordance with accepted design criteria.
3. Steel strength must comply with the minimum requirements of ASTM A 36(Fy=36 ksi,Fu=58 ksi),
ASTM A 572,Grade 50(Fy=50 ksi,Fu=65 ksi),or ASTM A992(Fy=50 ksi,Fu=65 ks).
4. Based upon minimum penetration depth of 0.46'(11.7 mm).
5. Based upon minimum penetration depth of 0.58"(14.7 mm).
6. Based upon minimum penetration depth of 0.36'(9.1 mm).
7. The fastener must be driven to where the point of the fastener penetrates through the steel.
8. Based upon minimum penetration depth of 0.35'(8.9 mm).
9. Based upon minimum penetration depth of 0.25"(6.4 mm).
z 10.For stepped shank fasteners:(Diameter of shank above the step)/(Diameter of shank below the step).
11.The allowable load values listed are for static load conditions.Refer to ICC-ES ESR-2138 and ESR-2811 code reports for seismic load conditions.

2.The allowable tension and shear values are for the fastener only.Members connected to the cold-formed steel
must be investigated separately in accordance with accepted design criteria.
3.Fastener is to be installed in the center of the stud flange.
4.Loads are based on cold-formed steel members with a minimum yield strength,Fy=33 ksi and tensile strength, Typical GDPSK
Fu=45 ksi for 33 mil(20 ga.)and 43 mil(18 ga.),and minimum yield strength,Fy=50 ksi and tensile strength,
