A SEICMIC UPGRADING TECHNIQUE FOR TIMBER STRUCURE WITH VISCO-ELASTIC TAPE
For the purpose of encouraging to seismically upgrade existent timber houses, we develop a newly simple and economical technique to improve seismic performance of timber houses by installing visco-elastic tape between columns, beams and boards made of gypsum and plywood.Vibration performance tests of simple substance of visco-elastic tape and shaking table tests of timber frame reinforced by visco-elastic tape are conducted to confirm the efficiency of this technique. For shaking table tests, test frames of gypsum board and plywood board are prepared with and without visco-elastic tape. We mainly discuss the results by equivalent viscous damping and strength of test frame that are calculated from load-deformation relations. Test results show considerable improvement of seismic performance due to visco-elastic tape. Dynamic characteristics of visco-elastic tape are mathematically modeled. Prediction technique is also proposed for a seismic upgrading design by visco-elastic tape. Predicted results meet good agreement with test results.
