The calculation also checks the stability of the wall for mainly vertical loading, at the half height beneath the concentrated load. Users of this program must determine the validity of the results.
The calculation checks the localized bearing resistance of the masonry directly beneath the load and will determine if a spreader is required.

The latest advances, materials, and techniques are clearly explained. This program is not intended to replace sound engineering knowledge, experience, and judgment.
Cantilever wall height limited to 6 ft.
Figure 1 illustrates the fact that masonry walls are responsible for 25% of the damage in buildings. Narrow brick wall – modification factor is 1.15 since wall is one brick thick.

The calculation also checks the stability of the wall for mainly vertical loading, at the half height beneath the concentrated load. Eurocode 6 requires a steel cross section larger than 0.03 % of the wall cross section and vertical spacing between bed joint reinforcement lower than 600 mm.
Bed joint reinforcement is introduced in the masonry simultaneously with the wall construction, meaning that almost no changes are made in the traditional technology for building masonry walls.
The original solution included apparent vertical and horizontal reinforced concrete elements embedded in the wall. U block in the horizontal element and for special two-large cells block for vertical element (if the r.c. Therefore, the alternative solution is faster to build and is more rational. The typical solution in these cases was based in reinforced concrete elements properly connected to the surrounding frame and placed inside pockets of the masonry units.
Typical maximum spans were given for panels with different reinforcement ratios. Top reinforcement: 2 consecutive courses. In addition, dowel bars were supposed to be placed at the base, every 0.40 m. Vc = 0.14 m × 0.17 m × 1 m / 1.20 m = 0.0198 m3 of concrete /m2 of wall. The original solution includes also a column, every 3.00 m. In the values above, the increase of productivity is not included. The usage of bed joint reinforcement can also allow building large size non-loadbearing walls, with better performance and lower cost. Therefore, bed joint reinforcement or other similar solutions should be adopted in areas of high seismicity. In the present time, masonry infill walls are considered to be non-structural building elements, while the seismic behavior of reinforced concrete frame structures having these type of walls, indicated a structural behavior of the infills.
Portugal, masonry is being mostly used as traditional in-fill material for reinforced concrete frames. This aspect can lead to severe cracking or even collapse of the veneer walls. Portugal, masonry is being mostly used as traditional infill material for reinforced concrete frames. A new construction system for masonry buildings using concrete blocks units and trussed reinforcement is presented here and its seismic behavior is validated through shaking table tests.
In reality, they can play a structural role in the overall seismic behavior of buildings. The adopted approach starts from material and technology development. Experimental and numerical characterization will be aimed at deriving structural requirements of masonry infill walls, as well as tools and methods for their assessment.
European churches and other monumental buildings has been the basis for our work. An overview of possible approaches for the numerical modelling of masonry structures is presented.
