Structural Performance of Tapered Tall Buildings
Kyoung Sun Moon
Structural efficiency of tapered tall buildings has well been recognized, and many tall buildings of tapered forms have been built throughout the world. This paper systematically studies the structural efficiency of tapered tall buildings in terms of lateral stiffness. Tall buildings of various heights and angles of taper are designed with different structural systems prevalently used for today’s tall buildings, such as braced tubes, diagrids, and core-outrigger structures. The heights of the studied buildings range from 60 to 100 stories, and the angles of taper studied are 1, 2 and 3 degrees.Based on design studies, comparative performances of the various structural systems for tapered tall buildings are presented.
