Abstract: The authors have developed a new method of seismic retrofit for steel structures by adding a knee brace which is jointed to the existing structures by vices made of high hardness metal screw bolts. The strength and behavior of the connection by the vice had been already studied in our previous paper. The features of the connection by the vice are easy set up and providing the strength as much as by the normal bolts joint. An experimental study has been conducted for the specimens of steel frames retrofitted by the knee braces. The knee brace was jointed to the specimen by the vices. Two types of failure modes were investigated. The former was slipping behavior of the connection and the later was bucking at the knee braces. The strengths of the specimens were estimated by the simple calculations for the two types of failure modes.
