Descripción
A procedure for the reinforcement of timber floor joists in ancient buildings using steel U shape cross sections screwed to timber from the upper side is described. Bending tests of 3 groups of 10 beams were carried out obtaining the stiffness and load carrying capacity. The first one was composed by pieces of glued laminated timber of Spruce with 180 x 200 mm cross section; the second one was of Scots pine sawn timber with the same cross section; and the third one was 120 years old solid timber beams of genus Pine with 130 x 150 mm cross section. Each group was divided in two groups of 5 beams. The first sub-group was tested without reinforcement and the second one was tested with the steel reinforcement. The reinforcement increases the stiffness from 45 to 98% and the load carrying capacity from 27 to 58%.
