Tuned Liquid Column Dampers for Structural Control

Structural vibrations from excitations such as wind, earthquakes, waves and pedestrian movements can be controlled using tuned liquid dampers such as tuned liquid column dampers (TLCDs). They benefit from low installation cost, ease of maintenance and amenability to tuning. TLCDs offer high volumetric efficiency and a specific and quantifiable damping mechanism.

This guide outlines passive, active, semi-active and hybrid forms of TLCD. It systematically covers basic operational principles, mathematical modelling, analysis methodologies of damper-structure systems, in frequency and in time domain, design issues and experimental studies, and structural implementations. There is also detailed coverage of innovative design variations that enhance applicability and performance.

This book is aimed at researchers in structural control, advanced students, and vibration specialists in industry.
