This document discusses special considerations and challenges in seismic design of tall buildings. It notes that tall buildings must be safe, secure, serviceable, reliable, and protective. Key challenges in tall building design include increased height and slenderness, unusual forms, smaller structural elements, and minimizing costs. The document discusses various lateral load systems and focuses on challenges in different height ranges of buildings. It also covers seismic and wind loads, dynamic response of tall buildings, modeling options, effects of podiums, and soil-structure interaction. The way forward is continuous improvement through research and practice.
