Abstract

This study presents the analysis procedure and results for the structural performances of twisted tall buildings under construction. Six sample models of 60-story twisted steel structure in diagrid system or braced tube system were selected, and design load requirements during construction for the buildings were analyzed. At construction stages of 20 stories completion and 40 stories completion, the structural behaviors for wind and seismic loads were presented and compared with those of completed buildings. Also, for load combinations of gravity loads, seismic loads, and wind loads, the design loads of structural members were calculated, and design strength ratios at construction stages and after completion were compared. The analyzed results may be used as guidelines for structural design or construction planning.
