MWM | Multi-storey Masonry Wall | Update Information

Version 02/17


The material database for the products of Schlagmann Poroton GmbH & Co. KG has been updated.

Version 01/17


The internal force graphs for the output document are scaled correctly now.

Version 02/16


Divergent wall thicknesses can be entered flush with the outer surface.
ÖNORM EN 1996: For partially superted ceilings the rules from the German Annex can be applied.
The material databas for the products of "Wienerberger GmbH" and the "Schlagmann Poroton GmbH & Co. KG" are updated.

Version 01/16


Wall overhang: An overhang beyond the edge of a plate or strip foundation can be defined. The design is done like for partial supported slabs according to DIN EN 1996.
Data exchange: Loads and wall geometry can be transfered to foundation programs FDS+ and FDR+.

Version 02/15


With the selection of DIN EN 1996:2015 new adjustments for the National Annex (A1 + A2) Part 1-1 and Part 3 are implemented. Main adjustments are the correction for compressive strength of masonry recipe.

Material update

The material database with material parameters for Germany has been updated according to the product approvals 2015.

Version 01/15


Technical adjustment

Version 01/14C

Material selection updated

The material selection form for masonry based on technical approvals and user definied masonry acc. to DIN 1053 and DIN EN 1996 have been updated. The form for approval based masonry now shows substantially more values for mechanical properties definied in the specific approval as well as verbal hints from the approval.

In case of user defined material a greater selection of derived mechanical properties (e.g. unit weight based on selected bulk density class) are shown.

When defining a standard material acc. to EN 1996 it can now be specified that perpend joints parallel to the wall face shall be assumed. This automatically toggles the neccessary reductions of the masonry compressive strength.

Version 01/14A


The load spreading areas underneath concentrated loads with only symmetrical load spreading enabled were not displayed correctly (design checks were not effected). In the simplified design method load centering strips were only taken into account at the top of the topmost wall.

Extension of product database

For DIN 1053 and DIN EN 1996 the product database now also contains all products of Schlagmann and HART Keramik.

Version 01/14

New: Eurocode 6 for Germany

Walls can now be designed according to DIN EN 1996 (general and simplified design methods). Background information to the changes in comparison to DIN 1053-1/-100 can be found in Frilo-Magazin 2012 (download available from www.frilo.eu/de/service/publikationen/frilo-magazin.html).

The following facts are worth mentioning:
- partially supported floor slabs are now an integral part of all design checks; this commonly reduces the load bearing capacity
- if partially supported floor slabs are present the resistance to lateral loads exhibits an significant dependency on the load direction; wind pressure is more favorable than wind suction
- due to a reformulation of the set back rule for load eccentricities at the top and the bottom of the wall utilization ratios of 1.0 do not indicate the load bearing limit; only utilization ratios > 1.0 indicate immanent wall failures

Version 02/11F

Basement walls

Crash during investigation of single basement wall acc. to the simplified design method fixed.

Version 02/11E


For walls supported at the top and the bottom only the effective length was not conservatively estimated if the following conditions were

met: DIN 1053-100, general design method, wall thickness min. 36.5 cm and floor slab supporting length less than half the wall thickness.

Version 02/11D


A program crash occuring during the design of basement walls acc. to the simplified design method has been fixed.

Version 02/11C

Internal modifications

Only internal modifications and adoptions were conducted.

Version 02/11B

Basement wall acc. to simplified design method

In the design of basement walls acc. to the simplified design method under certain circumstances an internal error was produced. This has now been fixed.

Version 02/11A

Visibility of utilisation ratio panel

The utilisation ratio table at the right screen border is now by default not visible. Its visibility can

now be toggled via the F12-key on the keyboard or the newly added eta-button in the main toolbar.

Version 02/11

Additional system views in the output documents

Optionally a side view and an isometric view of the loaded system can be added to the output document (see

output menu).

Graphical display of load dispersion areas underneath vertical loads

In order to identify differently loaded wall areas more easily a graphical hint of the load dispersion

areas underneath vertical loads of type concentrated load, block load and trapezoidal load has been added.

Version 01/10B

Internal modifications

This update includes internal modifications only, which have no effect on the program behaviour.

Version 01/10A

First release

The new program MWM is meant to replace the program MW1 in the long run. It is based on the same new core as MWX, MWK and MWP and allows the analysis and design of multi-storey mansonry walls according to DIN 1053-100 and EN 1996 (with national annexes of Austria, the United Kindom, the Netherlands, Belgium and the Czech Republic). Through the extensive use of context menues, editable dimensions and load labels it is possible to use the program interactively via the 3D-representation of the model.
