The use of steel rbs to increase ductility of wooden beams

In the present paper a rigorous analysis is developed in order to assure the protection of the beam to column connections and of all intermediate sections of the wooden beam when horizontal forces increase and steel “dog-bones” yield. In other words, the yielding of both “dog-bones” is promoted, leaving all the other sections in elastic range. The role played by vertical loads and by the amount of section reduction are accounted for, and in addition, the possibility that the beam to column connections are realized with a partial strength connection (a connection which is not able to transmit to column the whole plastic moment of the beam) is considered.
