One of key issues of recent seismic structural design for buildings is the safety performance against long duration earthquake, repeated earthquake and severe earthquake after main shock. It may be difficult for conventional shear walls of wood house such as bracing and plywood shear wall to survive during their earthquake.
In this study, shear wall with high stiffness rubber was proposed to prevent the degradation of seismic performance during repeated earthquakes and shear wall test and shaking table test were conducted in comparison with plywood conventional shear wall.
Following results were obtained:
1 In shear wall test, it was found that no degradation occurred in proposed shear wall in the range of 1/30rad.
2 In shaking table test, the specimen without proposed shear wall was damaged in three times severe earthquakes, while the specimen with it was survived in five times severe earthquakes.
