A system that controls the rocking behavior of multistory shear walls is proposed as an innovative damage-control system for cold-formed steel structures. In this system, we have developed a new hold-down equipped with a fuse function (HDF) that controls the rocking behavior, and is placed on the foundation of multistory shear walls. The HDF contributes to reducing damage to both structural and nonstructural members in cold-formed steel framed buildings, dissipating seismic input energy in the event of a large earthquake. The present paper describes the static tests performed using HDF specimens and folded-steel sheet walls specimens with the HDFs. It has been confirmed, from the test reuslts, that the shear walls systems using the HDFs have high energy-dissipating performance in comparison with the exiting shear wall systems.
