S.T.A.DATA 3Muri Pro v11.0.0.10

3Muri is a software for analysis of structures built in masonry and mixed materials through a non-linear (pushover) and static analysis. The strengths of 3Muri is its innovative computation method (FME) that is able to give more information on the structure’s real behaviour to seismic actions, aside an extreme simplicity of use.
3Muri offers a drawing area for insertion of the structure with intuitive controls, an engine for the creation of computation models and their solutions, and a post-processor for immediate presentation of the results and creation of the computation report.

3Muri was created by a joint project of S.T.A. DATA and the research group headed by Professor Sergio Lagomarsino, from the Construction Technique department of Genova University. Along with other specialists (eng. Andrea Penna and eng. Alessandro Galasco from Pavia’s Eucentre, and eng. Serena Cattari, Genova University) they finalized the theoretical aspects of 3Muri through laboratory’s experiments and analysis on real structures. That continuous collaboration guarantee an always updated software, completely operative and reliable for the most professional requirement.

Sensitivity Analysis
Sensitivity Analysis is a calculation method aimed to obtain better understanding of the structural functioning and accurate planning of the site investigation plan. As known, doubts during modeling directly affect the evaluation of seismic safety. A specific example is materials mechanical properties, usually defined on the basis of reference values and for which, through investigation, it aims to limit the inescapable uncertainty. Since the site tests have frequently high economic cost, the possibility to identify in advance (through the Sensitivity analysis) significant testing campaign points can limit investigation costs which result might not be of interest.

Overlapping capacity curves
This feature allows the designer to simultaneously refer to the capacity curves of more analysis on a single diagram.

3D modeling
To the current input in (2d) plan was joined a (3D) axonometric input mode, with the following characteristics. You can insert the structural objects directly in an axonometric view.

3D modeling is not developed only with the aim to provide an alternative to the already existing plan input but also provide a new mode of already allocated structures editing. Currently the elements properties multiple editing is easy in plan but less performing in elevation. The editing in 3D will simultaneously change the characteristics of the elements at different levels.

Specific applications of 3D editing
Following a multiple selection of structural objects (also on different levels), you can:

Align panels
It performs the concurrent editing of masonry walls with different thicknesses at different levels in order to align them with the same outer edge. This operation, that so far was carried out by placing in the wall properties the eccentricity value to be manually calculated, is now fully automated.

Assign wind exposed
The properties of a wind exposed panel can be assigned through a multiple selection.

Table editing
The editable table elements has always shown the characteristics of all the model's elements.

3D Filters-The Parts
Allows to transform groups of structural elements in defined parts. Working with parts makes easier the simultaneous editing phases of multiple elements. You can display one or more parts, called active parts, at once.
There are two types of parts: user defined parts and logical parts. The user defined parts are created by the user selecting the items that belong to the parties.
The logical parts are automatically created by the program, ordering the items in different criteria categories (material, elements).

Automatic detection of the thickness
During the input phase, you no longer have to worry about the various wall thickness in the different sections and perform the input with any thickness. In a second step a dedicated command (by tracing a segment that intersects the wall) automatically calculates the thickness by extracting it from the DXF file and assigns it to the already defined section.

Input by dimension lines
The input of the walls without the DXF background and without the need to use a coordinates box is possible through the cad dimensioning command with ability to directly enter the extension of the wall. The direction of the walls can be easily identified through the use of guidelines. The same dimensioning command is available for moving nodes, openings and concentrated loads.

IFC management – Output/Input
Export 3Muri to IFC Once you have finished creating the model, the command "IFC export" in the File menu allows to create the IFC file. This file includes the structural objects defined by the IFC standard in order to be visible with a player or BIM CAD.

Advanced importation
Runs the OpenCAD application, a CAD system that makes interoperability its strong point. With interoperability we mean the ability to cooperate and exchange information with the other products or services with resources's optimization. The information exchange takes place through various graphic formats: IFC, DGN (Bentley), DXF, SKP (File Sketchup), EMF, WMF, BMP, GIF , JPG/JPEG, TIF, DWG

Editing mesh
In mesh editing you can change the characteristics of the generated structure according to the design requirements. The access in the editing mesh area is achieved through the appropriate button on the command bar.

Walls' editing operations
Rectify walls: Allows to rectify the previously entered walls.
Extend/ Trim walls: allows to extend or shorten an already existing wall.
Fillet walls: Classic cad command for joining two walls that do not cross.
Stretch: This command allows to move an outer node of the wall.

Movement of the openings.
Selecting with the right mouse button allows to move an already inserted opening.
It is necessary to define the displacement vector by clicking on two points, the start and end point.

DXF file importation functions Cancel or easily move a DXF file translating it in the graphics area. These new functions are directly available by clicking on the right button of the mouse in the graphics area.

Editable elements table
The table appears by clicking on the proper button that shows the characteristics of all the information inserted by the user through the input windows while creating the model. The drop down menu bar on the left, facilitates the navigation in these tables. The main characteristic of this table is the fact that it can be edited. Every modification of the table brings the direct modification of the model`s characteristics.

Mesh display of the geometry
The graphics area is separated in two different areas, the plan on the left and on the right the view of the mesh of the selected wall. The selection of a wall is possible through a simple click on the plan.

Improvements for the management of the analyses` parameters.
The calculation window shows on the table the “essential” data necessary to describe the analysis, on the right the calculation parameters.

Better graphical interaction in the local mechanisms´ area
In order to load the view of the selected wall you can now click directly on the plan instead of using the drop down menu bar. The cad area of the plant and view have been improved for a better graphical management of the input phase.

Snap utility
The snap are manageable in a total parametric way through the buttons bar down on the right. They can be turned on or off according to the desired requirements
