摘要

Purpose

The work aims to equip an overhead water tank of a building with the triple functionality of conventional water storage for building water supply, reserve storage for firefighting, and lateral vibration control of the building under wind excitation. It entails the design of a plate appendage that is placed in the zone of impulsive liquid of the tank and the plate oscillation frequency is tuned to the predominant structural frequency.

Methods

The formulation of the structure-tank-plate problem in time domain is presented. A realistic example structure in the form of a 14-story apartment building is considered for the numerical study. The detailed design procedure of the plate appendage is illustrated. The vibration control effectiveness of the designed tank-plate appendage system is numerically assessed by subjecting the structure-damper system to ten synthetically generated wind excitations. The implications of detuning of the damper resulting from variation in the building stiffness are also examined.

Results and Conclusion

It is shown that a practically feasible configuration of the tank-plate appendage system is realizable that fulfils all three intended functions. Further, the system achieved significant reduction in acceleration and displacement response reductions of the structure under wind loading. For variation in building stiffness, the tank-plate appendage system remains effective in reducing the rms and peak acceleration as well as the rms displacement of the structure, indicating the robustness of the control performance.
