Reinforcement of Floors in Brick and Cement

The structural strengthening of floors in brick and cement is one of the most fieqnent interventions with the nse of pultruded sheets and lanunates in CFRP, because of the quick installation and several advantages to which they are associated. Strengthening can be necessary in several situations, such as oxidation, with consequent rednction of the effective section of reinforcement or, for instance, in case of a modification of

The structural reinforcement of floors in brick and cement is one of the most common applications of using pulbuded sheets or carbon fiber-reinforced polymer (CFRP) fabrics, thanks to the rapidity of application and the many advantages they offer. The reinforcement may be deemed necessary on several different occasions.

The reinforcement of the lower surface of joists of floors in brick and cement is usually realized by the use of pultruded sheets because of their easy lay-up nevertheless, the use of fabrics is also possible. The width of the sheets depends on the joist geometry and especially on the base of the latter the height may, on the contrary, vary according to the reinforcement area required. Several overlapping sheets may be used, but the choice of an excessive number of sheets should be avoided, in order...
