RESUMO

The splitting of the fair-faced masonry-structure are very usual but it is not wellknown the reason of its occurrence, although they are frequent, specially the ones that appear in the linking of the masonry-concrete column. The purpouse of this work was to study the best anchorage technique between masonrystructure, being evaluated its efficiency to prevent this type of splitting. Beyond the materials that are usually used for masonry (ceramic block, mortar etc), changeable materials of anchorage (stell welded tie and steel wire) and apparatus of linking (adhesive epoxy, bolts, washers and angle-steel) were used, analyzing the best combination for the technical view. Tests of characterization of the materials and the pullout test were made, until the occurrence of the first splitting visible by naked eye. Finally, it was concluded that the metallic wall tie, 15 x 15 mm and the diameter of wire 1,65 mm, without angle-steel and with mortar with acrylic adhesive in the concrete column was the best anchorage technique for to prevent occurrence of splitting in the fair-faced masonry-concrete structure
