Subject RIV: JM - Building Engineering

The paper presents two approaches using different retrofitting technologies. In the first case, the energy dissipation capacity is increased by adding mild steel rods inserted around the connecting the two parts of the halved joint. During the motion of the timber structure, the connected timber struts rotate mutually in the joint and tend to deform the inserted steel rods plastically, which absorbs the energy. It is obvious the no dismantling is necessary during the retrofitting intervention. In the second case, the connecting wooden pin is removed from the joint, the halved parts are slightly opened, and two thin plates are inserted into the opened slot and are stuck to the wooden elements. The plates are made of a material with a high fiction coefficient. Disc brake plates or even thin oak plates can be used.
