FTAO Analysis for Complex Shear Wall Openings
Featuring Terry Malone, PE, SE, WoodWorks
Current methods of Force Transfer Around Openings (FTAO) analysis only allow for openings of the same height in exterior shear walls. However, today’s penchant for more openings of different sizes requires a more flexible method that allows for more complex wall layouts. The original method of FTAO analysis was developed by Edward Diekmann in the early 1980s, and other approaches have since been developed, modified and simplified based on his original method and full-scale testing.
This presentation will demonstrate another modification to FTAO analysis that will allow complex shear wall opening configurations, accommodating the addition of gravity loads, shorter tie straps, and any combination of opening heights using the transfer diaphragm approach.
