| Why This Course Matters As buildings become taller and more flexible, structural behaviour changes significantly. Wind and seismic actions become increasingly influential, dynamic effects become critical, and design decisions must account for drift, torsion, vibration, stability and the interaction between different lateral-load-resisting systems. High-rise engineering also introduces challenges that are less significant in conventional buildings, including resonance, higher-mode response, weak and soft storeys, differential column shortening, second-order effects and global instability. Understanding these behaviours is essential for developing structural systems that satisfy both strength and serviceability requirements. This course develops the engineering judgement required to evaluate these issues systematically, linking structural dynamics and code-based analysis with practical high-rise design and construction considerations. |

This module introduces the structural definition of high-rise buildings, emphasising that classification is governed by structural behaviour rather than height alone. It explains how, as building height and flexibility increase, lateral loads such as wind and seismic forces begin to dominate the structural response and govern design decisions. This transition shifts the design approach from gravity-controlled systems to structures where dynamic behaviour influences stiffness, core performance and overall stability, requiring more advanced analysis and design methods.
Examine the gravity, wind, seismic and other actions that influence high-rise structural design. The module addresses dead and live loads, lateral-load effects, load combinations and the increased importance of load-path clarity, serviceability and stability in tall structures.
Develop a foundation in structural dynamics by examining how structures respond to time-dependent loads. Participants explore mass, stiffness, damping, equations of motion and the fundamental differences between free, forced and transient structural response.
Explore the behaviour of an undamped Single Degree of Freedom system governed by mass and stiffness. Learn to determine natural frequency, period, displacement, velocity and acceleration while understanding the conservation of mechanical energy during free vibration.
Develop the general mathematical solution for undamped free vibration and examine how initial displacement and velocity determine structural response. The module covers amplitude, phase, natural frequency, period and the relationship between displacement, velocity and acceleration.
Examine how damping dissipates energy and changes structural vibration over time. Participants study underdamped, critically damped and overdamped systems, damped natural frequency, response decay and the role of damping in realistic structural behaviour.
Analyse the response of an undamped SDOF system subjected to harmonic loading. Explore transient and steady-state response, frequency ratios, dynamic amplification and resonance, and understand why resonance must be carefully considered in structural design.
Learn how arbitrary and time-dependent dynamic loads can be represented using the principle of superposition and Duhamel’s Integral. Participants will understand how previous load impulses contribute to the structural response at any point in time.
Progress from single-degree systems to realistic structural models with multiple independent motions. Develop mass and stiffness matrices and formulate coupled equations of motion for MDOF systems representing multi-storey structures.
Explore modal analysis as a method for transforming coupled MDOF equations into independent modal equations. Participants examine natural frequencies, mode shapes, modal coordinates, orthogonality and the reconstruction of physical structural response.
Apply numerical techniques to dynamic structural problems that cannot be solved conveniently using closed-form analytical methods. The module introduces time-stepping procedures, including the Central Difference and Newmark methods, for calculating structural response over time.
Examine how structures respond to earthquake ground motion and how seismic effects are incorporated into structural design. Participants explore response spectra, modal response combination, base shear, drift and ductility, together with concepts such as energy dissipation, base isolation and performance-based seismic design.
Understand how wind tunnel testing is used to evaluate complex wind effects that conventional code procedures may not fully capture. Explore pressure distribution, base forces, torsional response, acceleration, façade loading and occupant-comfort considerations for tall and aerodynamically complex buildings.
Explore how outrigger systems connect the structural core to perimeter elements to improve lateral stiffness, control drift and reduce overturning demand. The module examines structural behaviour, wind and seismic considerations, analytical modelling and the practical coordination challenges associated with outrigger levels.
Evaluate critical high-rise performance checks, including inter-storey drift, torsional irregularity, soft-storey behaviour and second-order effects. Participants learn how these checks influence serviceability, occupant comfort, façade performance and overall structural stability.
Understand the distinction between a weak storey and a soft storey by focusing on lateral strength rather than stiffness. Learn how weak storeys are identified, how strength discontinuities affect seismic behaviour and which strengthening strategies can improve structural resilience.
Examine elastic shortening, creep and shrinkage in vertical concrete elements and understand how their cumulative effects can produce differential shortening in tall buildings. The module addresses prediction, construction compensation, monitoring and the impact on slabs, façades, partitions, elevators and building services.
Explore global instability in tall and slender structures and the influence of building slenderness, lateral stiffness and P-Delta effects. Participants examine buckling modes, structural systems vulnerable to instability and design strategies involving cores, bracing, outriggers and second-order analysis.
Examine how structural systems influence the construction sequence of tall buildings. The module explores core-first and integrated construction strategies, formwork systems, equipment and crane planning, site logistics, safety and the coordination required between structural, architectural and MEP works.
