A method of reducing the width of cracks in masonry

摘要

The invention relates to a method to reduce the width of cracks that may be induced in masonry. The method comprises the step of reinforcing at least one joint with reinforcement strips. The reinforcement strips comprise at least two straight, substantially parallel reinforcement wires connected to each other by means of a wire connecting structure. The reinforcement wires have a design yield strength f yd equal or higher than 550/³ s N/mm 2 and an equivalent diameter d equal or lower than 4 mm. The reinforcement strips have a resistance F against loads applied on said reinforcement strip. The resistance F has a design value of resistance F d . The reinforcement strip embedded in said joint has a bond capacity F bok . The bond capacity F bok has a design bond capacity F bod . The design yield strength f yd and the diameter d of said reinforcement wires are chosen in such a way that the design value F d of the reinforcement strip is equal or lower than said design bond capacity F bod of the reinforcement strip. The reinforcement wires are provided with ribs. The invention furthermore relates to reinforcement strips and to masonry reinforced with such reinforcement strips.
