I have a unique building - single story warehouse that is 210,000 sq feet that is about 85'-0" tall - and I am designing the temporary bracing for it for erection. My issue is that in the short direction of the building, the loads show that I need either (3) 3/4" diameter 6x19 IWRC EIPS Cables or (2) 7/8" diameter cables. On most normal buildings, I have only used cables up to 5/8" diameter. I think I am mostly worried that the heavier cable require more tension to straighten which might make plumbing the building more difficult. Is there any problem with just specifying these larger diameter cables?
Also, with the tall height, is it acceptable to still use the procedures in the AISC Design Guide 10? ASCE 37-14 indicates that seismic bracing is for buildings 60'-0" and under, but the commentary C6.5.2 says: "Designers of temporary bracing systems taller than 60'-0" should use rational approaches that are acceptable to the authority having jurisdiction." In my situation, I was likely going to use the exact same procedures (cable braces at each column line in each direction) to brace the building as that seems like a rational approach. For the load I am looking to put on these cables, the PL/AE is approximately 8" under ultimate loads, which isn't too bad considering it is 85'-0" tall.
Thanks for any insight anybody is able to provide.
