Use in notable structures
S-FRAME Analysis and S-CONCRETE were used to create structural models of the Burj Khalifa, currently, the world's tallest building, designed by Chicago, Illinois-based Skidmore, Owings & Merrill LLP (SOM). Bill Baker, Partner at SOM, discussed the use of S-FRAME in his keynote at the 2012 Structural Engineers Association of British Columbia (SEABC) Annual General Meeting, stating that SOM used S-FRAME as it was the program with which their in-house optimization software integrated.
