Abstract

AbstractThis paper introduces the ‘mega structure’ concept for supertall buildings. This concept incorporates the latest technology for structural energy dissipation and control systems, which are capable of predicting, controlling and modifying building motion/response. The implementation of tuned mass dampers (TMD) on a 150‐story building in Los Angeles is presented. Following a brief introduction to the underlying mathematical theory of TMD, the dynamic response of the building structure is presented demonstrating the effectiveness of TMD in suppressing undesirable building motions. The influence of the TMD configuration on global system efficiency is also investigated via parametric studies.
