SHAKING TABLE TEST ON A NOVEL GFRP WALL DAMPER
This paper reports shaking table test results for a novel pultruded cellular GFRP wall damper.A GFRP wall panel is capable of resisting vertical loads similar to other conventional structural walls.However,adding water to its hollow cells makes it possible to function as a Tuned Liquid Wall Damper to mitigate multi-hazards,e.g.,wind or earthquake.To this end,all cells inside the GFRP panel are connected at the bottom,allowing water to move through.The damping force can be provided by the head loss of the water that flows through orifices between the cells.Shaking table tests on the GFRP panel wall filled with various amount of water under two different ground excitation motions were conducted.Test results show that the vibration caused by the ground motion can be averagely reduced by 13%due to the damping effect provided by the GFRP wall panel.Therefore,it is promising to use the GFRP wall panel as a load carrying member and Tuned Liquid Wall Damper.
