Abstract
This paper describes the reinforcement of timber floor joists in old buildings using steel crosssections connected to timber from the upper side of the flooring. The reinforcement consists of a Ushaped steel cross-section with plates inserted into the timber and connected by means of screwing. For experimental verification 30 beams were tested by bending, obtaining the stiffness and load carrying capacity. The specimens were divided into three groups of 10 pieces each: the first one of glued laminated Spruce timber with a cross-section of 180x200 mm; the second one of sawn Scots pine timber with the same cross-section and the third one of solid timber Pine genus beams with a cross-section of 130x150 mm, from a 120 years old building. The reinforced beams had an increased stiffness of 45 to 98 % and an increased load-bearing capacity of 27 to 58%. FEM was highly valuable and effective in the design of the reinforcement.
