Strurel is a complete software package for structural reliability assessment. Strurel has its roots in the research conducted at the Technical University of Munich (TUM). Over the last three decades, researchers at TUM have developed reliability methods that have become standard practice in the structural reliability community. The methods and algorithms implemented in Strurel have undergone extensive testing within over 20 years of development. Strurel users include a number of international leading companies in structural, geotechnical and mechanical engineering. The features of Strurel include:

  • Suite of solution algorithms
  • Advanced stochastic dependence models
  • Enhanced sensitivity analysis
  • System reliability capabilities
  • Partial safety factor computation
  • Bayesian updating of reliability
  • Reliability-based optimization
  • Time-variant reliability analysis
