In addition to masonry that is subjected mainly to compression, you can also check walls that are subjected to horizontal forces in the direction of the plate or slab, thus enabling the analysis of bracing plates.
Basis of calculation
Calculations can be based on the following standards
- EN 1996-1-1:2006 (more accurate calculation)
- EN 1996-3:2006 (simplified calculation)
Types of masonry
According to EN 1996, the material parameters have to entered in line with the national stipulations.
Safety concept
The general requirements on load-bearing structures as defined by EN 1990 form the basis of the calculation in accordance with EN 1996-1-1.
System options
In addition to individual walls you can select the structural systems of
- basement walls
- intermediate storey walls
- top storey walls
for the calculation You can define ceilings to be supported on the left, the right or both sides. Also projecting ceiling slabs (for balconies) are definable. In this case, it is always assumed that the wall to be verified is covered on its total top surface by a solid ceiling and supports it.
Actions
The masonry wall to be verified can be exposed to vertical effects of actions resulting from
- wall loads from storeys above
- concentrated bearing loads at the wall head
- ceiling loads
and/or horizontal effects resulting from
- wall loads applying perpendicular to the wall plane (e.g. due to wind and earth pressure)
- bracing loads applying parallel to the wall plane (e.g. due to wind or inclination).
Combinations of actions
MWX generates automatically the appropriate load cases and load case combinations depending on the defined effects and performs the necessary analysis, whereby the decisive load case combination is determined for each individual analysis.
Design
The design is performed by means of a structural safety analysis for the defined system in accordance with the engineering code selected by the user. When applying the simplified calculation method, MWX checks compliance with the limits of application. If these limits are not adhered, you can apply the more accurate calculation method.
Analysis
The following analyses are performed depending on the selected code and the effects of actions that apply:
- Compressive stress
- Slab shear
- Plate shear
Each analysis is performed in the ultimate limit state. The underlying load combinations are indicated.
Output
Comprehensive adjustment options allow you to control in detail the calculation and the output of system, load and result values.
