An investigation is made of the possible application of tuned liquid column dampers and tuned liquid column/mass dampers in reducing the along‐wind response of wind‐sensitive structures. The structure is modeled as a lumped mass multi‐degree‐of‐freedom system taking into account both bending and shear. The wind turbulence is mqdeled as a stochastic process that is stationary in time and nonhomogeneous in space. A random vibration analysis utilizing transfer matrix formulation is carried out to obtain response statistics. The nonlinear damping term in the fundamental equation of the tuned liquid damper is treated by an equivalent linearization technique. Numerical examples show that tuned liquid dampers, which have significant practical advantages, are as effective as the traditional tuned mass dampers if the parameters of the liquid dampers are properly selected. However, excess liquid motion in a …
