Development of high-ductility high-damping shear wall for steel framed house and its basic mechanical properties

We developed a shear wall which exhibits high-ductility and high-damping structural performances when used in steel framed houses. The high ductility can be achieved by fastening plywood with drill screws inside the peripheral steel frames, preventing the plywood from dropping out. The high damping capacity can be achieved by installing the frictional energy-absorbing devices between the stud and inserted plywood panel. We conducted a series of static loading tests and a shaking table test. We also conducted analytical studies on 2-story house models, and confirmed that the wall is quite effective both for reducing the number of walls and suppressing the responses to severe earthquake ground motions.
