Ε. LOAD-BEARING MASONRY REINFORCEMENTS

22 CHAPTER E: ' LOAD-BEARING MASONRY REINFORCEMENTS' The user can select materials from among the three available companies to automatically fill in the compressive strength Fgr,c. Alternatively, he can fill in this value manually. Then he chooses the type of masonry - single-layer, double-layer or triple-layer. In the first two cases, the user is asked to calculate the ratio of the volume of grout introduced (voids to be filled) to the total volume of mortar (percentage of voids), n. In addition, the user selects the coefficients f0 and λ. In the case of the three-layer masonry, the following window is activated, as the new compressive strength is calculated only from the ratio of the volume of the two external sidewalls (or the volume of the grout to fill gaps) to the total volume of the masonry (percentage of gaps)
