S.T.A. DATA offers software and services for structural calculation. Practical, truly operational tools, created by a team of expert professionals, to solve every need.
In addition to the main module, dedicated to the global verification of the structure, the following optional modules are available to expand the software. In this way, it is possible to purchase only the functionalities that are really needed, with an effective costs optimization. At the same time, you can expand 3Muri Project with new modules at any time.
The additional modules available for 3Muri Project software are:
Local Mechanisms
If box-like behavior is not guaranteed, due to the lack of connections between floors and walls, the verification of local mechanisms is required: i.e. checking for possible detachment of walls out of the plane.
The Local Mechanisms module allows this verification by using the model employed for the global verification (carried out with the main module).
Once the model has been completed with the geometric data, loads and constraints, the software has all the necessary elements to carry out the local verifications. The designer will only have the task of indicating the zones concerned.

Steel Connections for 3Muri Project
The Steel Connections module enables automated verification of steel connections directly within 3Muri Project, optimising workflow and ensuring fast, efficient analysis. With a wide range of available connection types, it meets the main project requirements at a competitive cost.
In addition to a complete calculation report, the module provides detailed DXF drawings, enhancing both technical documentation and the construction process. It can also verify connections in structures modelled or designed with other software, increasing operational flexibility.

Time History Module – Nonlinear Dynamic Analysis
The Time History Module uses time accelerograms to accurately simulate a structure’s response to seismic events by simultaneously applying accelerations along the X and Y axes. This ensures a realistic and reliable analysis, identifying critical zones and directly calculating the maximum required displacement (Dmax) without relying on simplified methods.
Through integration with pushover analysis and management of multiple seismic scenarios, the module supports comprehensive seismic risk assessment. Advanced tools for accelerogram customisation and spectral compatibility checks make it an essential solution for structural design.

Sensitivity analysis
The calculation of existing masonry structures is particularly complex due to the uncertainties of the entities involved, such as element stiffnesses, strengths, geometries.
The problem is to quantify this uncertainty which, although impossible to assess in absolute terms, can be measured in relative terms, i.e. through the weight of each individual variable in relation to the others.
For example, if the collapse is determined by the low stiffness of the floors, it is pointless to carry out in-depth investigations on the masonry, after having verified that its incidence is insignificant.
The objective of sensitivity analysis is to provide a better understanding of structural behavior, by identifying the parameters that have the greatest impact on the calculation.
The main advantages for the designer are: the identification of the most probable causes that lead to the collapse mechanisms of the structure, more reliable results, investigations and targeted interventions on the most significant parts, reduction of investigation costs and interventions for adaptation or improvement.
The first step in sensitivity analysis is the identification of groups of parameters that the designer wants to analyze.
Each group of parameters relates to a structural characteristic (for example: vaults, floors, concrete, steel) and is made up of a set of data that can vary within a given range.
Subsequently, numerous non-linear analyses are performed automatically, highlighting the importance of the individual structural characteristics in the overall behavior of the building.
A final statistical evaluation allows to obtain values that are most likely to be reliable.

Multithreading and sparse matrices solver
The multithreading and sparse matrices module allows the use of two different calculation settings with regard to the processor: the selection of dense matrices or sparse matrices calculation methods and the multiprocessor.
Performing operations using the sparse matrices calculation method can lead to a significant reduction in calculation time and to a lower memory usage, due to the compressibility of the sparse data.
The multithreading module allows each analysis to be directed to a different processor on the PC, with great time saving.

IFC Module
The IFC module allows import and export in IFC format, to enable interoperability between different designers.
IFC Import
3Muri Project allows interoperability with BIM technology through the IFC (Industry Foundation Classes) format, whose specifications are based on a neutral data format specifically designed to describe, exchange and share design information.
3Muri Project provides the import of geometries from IFC models using the BIM Inside application, which is included in the module. In this way, the geometries of the objects can be used for the construction of the model.
IFC export
Once the creation of the model is finished, the direct export of the entire model in IFC format is possible.
This file contains the structural objects defined in the model, with the IFC standard, that can be read by other software, such as Revit®, Allplan®, Archicad®.
