Abstract:In this paper, a new idea for designing the metallic yielding-friction damper (MYFD) is presented based on the principle that the metallic plate can be used for yielding and can be the friction component of the passive energy dissipation device (PEDD). This type of damper is so-called the MYFD, because it consists of yielding part and friction part. Phased energy dissipation is realized throughout the metallic yielding plate and friction plate combination where friction behavior is prior to yielding behavior. The quasi-static test with two small-scale MYFDs is carried out. Then, it is applied in an actual reinforced concrete building. The design method and fitting process of the MYFDs are introduced. In order to compare seismic responses of the building with and without the dampers, a dynamic analysis of the building under earthquakes is performed. The results show that the MYFD presented here possess good ability of seismic energy dissipation.
