Chapter 1 - History and Global EvolutionFrom tall masonry and early steel frames to tubes, outriggers, mega-frames, damping and sustainability. The chapter establishes what actually makes a building 'tall' - slenderness and dynamic sensitivity, not storey count - and introduces the scaling arguments that explain why lateral response overtakes gravity as height grows.Its most useful contribution is the distinction between code permission and code sufficiency: the fact that a code contains a system in its tables does not mean the code was calibrated for your building. Chapter 2 - Core Design ConceptsThe argument that tall buildings are governed by coupled global behaviour rather than isolated member design. It separates the gravity and lateral systems, then works through the stiffness-strength-ductility triad.The chapter’s highest-value section is on drift: two measures are routinely confused in practice, and the chapter is explicit about which governs and why the deflection amplification factor must be handled consistently. It then covers occupant acceleration and wind comfort, PΔ and second-order stability, higher modes, and differential shortening.Chapter 3 - Structural SystemsThe chapter is unusually direct about delivery: it plots lateral efficiency against delivery complexity and argues that the right answer depends on the fabrication ecosystem and review capacity available, not on which system is theoretically most efficient.Chapter 4 - Wind EngineeringFor major towers, wind is a dynamic serviceability and comfort problem, not only a base-shear problem. The chapter builds the design wind climate, explains precisely why code wind is necessary but not sufficient for a flexible tower, and treats vortex shedding and lock-in, directionality and surroundings, and aerodynamic mitigation through shaping.Chapter 5 - Earthquake DesignPrescriptive base-shear design must be supplemented by performance thinking. The chapter establishes the seismic setting, explains why prescriptive design is insufficient for towers, and introduces performance-based seismic design with its hazard levels and acceptance criteria.Response control follows: isolation and damping, why isolation suits a stiff short-period structure such as the Los Angeles City Hall retrofit and is a poor fit for an already-flexible supertall.Chapter 6 - Geotechnics, Foundations, and SSIThe soil is part of the tall-building structural system. Foundation strategy, soil-structure interaction, liquefaction triggering, and deep excavation with diaphragm walls.The Millennium Tower is the case study, and it is used for something sharper than a cautionary tale: every individual check on that building passed, and it tilted anyway. The chapter turns that on the reader - which of your checks would have caught it, and if none would, what does that say about the checklist?Chapter 7 - Building SubsystemsFire, lifts, façade, services and carbon as first-class engineering decisions rather than someone else’s problem. Fire safety and egress, including the ASET-RSET margin and why an available margin is not an acceptance criterion; vertical transportation and handling capacity; façade racking and movement tolerance; MEP risers; and embodied carbon with the mass-timber horizon.Chapter 8 - Delivery and Constructability RiskThis is the chapter most absent from comparable texts, and the one practising engineers tend to find most immediately useful.Chapter 9 - The Road AheadA well-built tall building is defined by performance, not only height. The practice gap, a peer-review framework, benchmarking a market’s tall-building maturity, and a readiness checklist with explicit stop conditions.
