The 2nd International Conference on Uncertainty Quantification in Computational Sciences and Engineering (UNCECOMP) took place at Rhodes Island, Greece. We presented the different modules of Strurel.
Abstract: Strurel is a leading commercial general-purpose software package for probabilistic modeling and structural reliability assessment. Strurel includes software modules with state-of-the-art computational methods for component and system reliability analysis. These include the First and Second Order Reliability methods (FORM/SORM) and sampling based method including Monte Carlo simulation, subset simulation, importance sampling, line sampling, directional simulation and adaptive importance sampling. Strurel can handle static as well as time-dependent problems, and supports a wide range of probabilistic models encountered in structural reliability. It also includes a set of tools for the calibration of safety factors in structural design. Strurel comes with an easy to use graphical user interface and additionally enables coupling of limit-state functions with user-defined system models through an interface with external programs.
The computational core of Strurel has been coupled with the finite element package SOFiSTiK in a new module called RELY that comes as part of the SOFiSTiK software package. RELY is specifically designed to perform reliability analysis employing SOFiSTiK finite element models. In RELY, the engineering system of interest is modeled using the full capabilities of the SOFiSTiK finite element package; existing SOFiSTiK finite element models can be readily employed for reliability analysis.
We demonstrate Strurel and RELY on two example applications. Firstly, a reliability analysis using a limit-state function for a pressure vessel coded in Matlab is conducted in Strurel. Secondly, a reliability analysis of a design concept for a submerged floating tube bridge is performed with RELY.
