The 2012 edition continues to base its design loadings on SEI/ASCE 37-02, however, the wind loadings are now based on ASCE 7-10 provisions. ASCE 37-02 will adopt the ASCE 7-10 wind provisions in the next revision to the publication. In addition, it is very likely that many, if not all local building codes, will endorse ASCE 7-10 in the near future. As such, the TCA decided to endorse ASCE 7-10 as the standard for temporary bracing of Tilt panels during construction.
The major changes to wind load provision of ASCE 7-10 include:
Introduction of new wind speed maps to be used with a 1.0 load factor for LRFD designA 0.6 load reduction factor for ASD designRe-introduction of Exposure D in hurricane prone Regions
