The past, present and future of vibration serviceability: from an obscure subject to a governing design criterion and major expenditure

08 Oct 2019
Energy & HVAC Hub
- Hall 12

Vibration serviceability currently governs the design of many civil engineering structures from tall buildings to open plan, long span office floors. Somewhat surprisingly, it is no longer strength but vibration that determines the size and shape of modern structures. Architectural drive for slender and ‘transparent’ structures coupled with improvements in construction materials and technology have resulted in modern tall, long and lightweight structures. However, sufficient strength does not mean sufficient structural stiffness, mass and damping.

Basic laws of physics mean that such structures are now much livelier when excited by the same dynamic loading, yielding rapidly increasing problems with vibration serviceability of modern structures. When such problems occur in practice they are very difficult and expensive to remedy.

Alex will present examples of these problems and explore the strategic failure of vibration serviceability requirements in modern structures.  He addresses the issues, and explains how novel and customisable human-centred design for vibration serviceability and active control technologies can transform design by replacing outdated guidelines and ‘structural modifications’ to meet increasingly stringent vibration serviceability requirements in modern buildings.
