Reduced Equivalent Static Wind Loads for Tall Buildings with Tuned Liquid Dampers

摘要：

　　The tuned liquid damper (TLD) is a proven and an increasingly popular auxiliary device for mitigating the dynamic effects induced by wind loading on tall buildings.As buildings become taller, lighter, and more flexible, there is a greater contribution from the dynamic component.The most reliable tool for assessing the dynamic component is wind tunnel testing.A boundary layer wind tunnel is capable of accurately calculating an equivalent static wind load (ESWL) acting on a building.The current study investigates the reduction in the ESWL of a lateral-torsional coupled building with a TLD system installed.The building is sensitive to torsion in the first two vibration modes.The current investigation uses three unique multi-modal TLD systems designed specifically for a lateral-torsional coupled building.The building ESWL is evaluated with the TLD systems using measurements from tests conducted at the Boundary Layer Wind Tunnel Laboratory at Western University.
