EXPERIMENTAL INVESTIGATION ON THE PERFORMANCE OF THE RECTANGLE TUNED LIQUID DAMPER IN STRUCTURAL VIBRATION CONTROL
-
摘要: 介绍了矩形浅水TLD的减振机理和工程应用。通过4层钢架在简谐荷载作用下的试验研究,比较了该钢架在受控前和受控后的位移、加速度反应,表明TLD对结构低频振型具有比较好的减振作用。Abstract: It is presented that the vibration attenuation mechanism and the practical engineering application of the rectangle shallow Liquid Damper. Through the experimental investigation on the 4-floor steel frame under harmonic excitation, it is also compared the deformation and acceleration response without control and with control, and is concluded that the TLD system can control the first and second vibration modal of the structure effectively.
