The 2023 release of STRUREL including Comrel, Sysrel and Costrel comes with considerably improved handling of interfaces to Maplesoft Maple, Wolfram Research Mathematica, MathWorks Matlab, Python, Ruby, GNU Octave, R, Scilab and newly developed Aptech GAUSS engine. A Script Editor with syntax highlighting and extended folding for all scripting languages and deep error tracing is implemented. STRUREL can now handle MAT and HDF5 files. Before one runs a changed script the engine will be automatically restarted. Furthermore, there are: Retranslator Mathematical Formulas (RMF), a Help system based on PDF standard, context sensitive help for the Symbolic Expressions Editor, simplified interface functions to all engines, comfortable Run control. The new SAO-Creator allows to easily build STRUREL custom Add-Ons. Each standard interface now can generate a Run Script file that encloses all steps of a reliability analysis using the language of the corresponding engine. Therefore, it is possible to execute a bundle of a Run Script together with the corresponding script of the state function on Windows, Linux and macOS without invoking STRUREL software.
STRUREL is a collection of programs for stuructural reliability analysis. More details can be found here.
The core package is COMREL for component reliability analysis.
The additional package is SYSREL for system reliability analysis.
The next additional package is COSTREL for reliability based optimization.
In reliability analysis, the goal is to assess the performance of models of varying complexity. Additionally to internal Symbolic language, STRUREL allows you to use limit-state functions coded in Maple, Mathematica, Matlab, Python, Ruby, Octave, R, Scilab or Gauss.
As a demonstration of the new capabilities we have taken from literature a well known example-structure: a plane truss with 23 bars and vertical loading. The failure criterion was deformation greater 11 cm in the middle of the lower girder. This example was analysed by all 8 engines with identical results in terms of probaility of failure. Additionally, for extended visualisation, deformations plot were realised using graphical facilities of the corresponding engine.

You can develop your own STRUREL Add-Ons using SAO SDK or the integrated SAO-Creator to achieve external environments by interfaces implemented in STRUREL. State-of-the-art reliability methods of STRUREL are used in module RELY of SOFiSTIK also. More details can be found here.
MAT and HDF5 files can be used to store or load scalars, vectors or matrices within the external scripts linked to STRUREL. These files are primarily used in the context of Matlab, but can also be accessed from Python, Maple, Mathematica, Ruby, Octave, R, Scilab or Gauss.
We analysed a complex spatial truss taken from literature.
On the education page, you will find a series of video tutorials that demonstrate the use of the STRUREL programs.
Due to material deficiencies and changes in safety requirements, existing overhead transmission towers must undergo a verification of their reliability. STRUREL powers the software P242 for FE based reliability analysis of these towers, which was developed in collaboration with major German electrical infrastructure companies. Due to its user-friendly and effective design, the software is used efficiently to verify 1000s of transmission towers.
STRUREL supported the design and manufacturing of critical components of aerospace structures, including the high-strength steel booster case of Ariane 5 for which an exhaustive reliability assessment was performed. The reliability updating capabilities of STRUREL allowed optimizing the expensive proof-tests that are part of the manufacturing process.
STRUREL was central in verifying and demonstrating the reliability of the Storebæltsbroen cable bridge. The effect of cable failures on the reliability of the bridge was investigated with the unique system reliability tools incorporated in STRUREL. These allow to efficiently assess systems with large numbers of failure modes.

Actions on structures such as wind, earthquake and machinery vibrations, as well as the capacity of structural elements, the material properties, and the geometry of a structure are typically not known with certainty. STRUREL can account for all types of uncertainties and offers a powerful tool set for setting up probabilistic models of engineering structures/systems.
Download the largely extended demo version of STRUREL 2023 today! See how to visualize results using interface built-in plotting facilities or additional libraries such as matplotlib, tkinter, ggplot2 and more. Test our efficient implementation of state-of-the-art methods for structural safety.
Our software product STRUREL is the indispensable tool for working with probabilistic models. STRUREL allows to efficiently assess the risk/reliability associated with engineering structures/systems - even if the underlying engineering model is computationally expensive to evaluate. STRUREL was founded at the Technische Universität München (TUM) and has been developed and tested for more than 30 years.
