Description

265’ Air Traffic Control Tower Using Antiterrorist Bomb Blast Security Criteria




“The professional help from SidePlate® was beyond expectation. ‘That’ made a difference.”

– Silvano Patrignani,

XL Ironworks

Challenges
  • To satisfy the FAA’s Antiterrorist Bomb Blast Security Criteria using a braced dual system for the steel frame tower for improved economics and security
  • Project budget and schedule precluded the use of other connection systems without additional testing due to SAC’s imposed limitations on the extent of their prequalification
Solutions
  • SidePlate’s unique versatility allowed the use of its SureBrace2™ connection system, which combines a moment frame with a super X-braced SCBF connection system to take advantage of unlimited column depth prequalification (W27x cruciform column used) for maximum economy and robustness.
