Performed the frame analysis and design to verify the structural adequacy of the high-risk steel erection construction work for the pedestal and core structure that form as the base of a skyscraper that will eventually rise 995-ft tall. The pedestal steel frame cantilevers 42-ft from the concrete core, erected sequentially around it creating multiple unbalanced conditions at certain instances. Recommended the enhancement of the permanent steel frame embedded at the core and introduced additional temporary bracings to mitigate the overstressing of the permanent steel members due to construction sequence loadings.
