Task Group 1.4

Probabilistic Non-linear Finite Element Modelling – Reliability and Safety Formats

Mission Statement/Objectives
Traditional deterministic methods are not sufficient to properly design and assess new and existing general or advanced engineering structures and their components, which are subjected to variety of complex loading conditions from natural and artificial environment.

Because of uncertainties in loading conditions, material behaviour, geometric configurations, and boundary conditions, the stochastic analyses techniques (which accounts for all these uncertain aspects) must be applied to provide rational reliability analyses and to describe realistically the existing behaviour of engineering structures.

Therefore, stochastic analyses techniques and its proper application for engineering structures requires an education programme/guideline that is portable, provides global acknowledgment, improves structural performance and sets benchmarks within the industry.

Scope & Limitation
TG1.4 focuses on systems, continuum mechanics, engineering structures, static and dynamic aspects, time dependent aspects, linear and non-linear material and system aspects, finite element methods (FEM), discrete element methods (DEM), and associate methods, partial safety factor and reliability index/probabilistic based safety formats. TG1.4 does NOT focus on design, systems with large deformations and large non-linear effects, load models, structures made of timber, soil systems.

Expected Project Output

  • Documentation of the round-robin modelling campaign - a collection of technical papers for an in-depth information on deterministic & probabilistic non-linear finite element methods applied on 1D structural elements like columns, beams and trusses
  • “Probabilistic Non-linear Finite Element Methods” Guideline: a Structural Engineering Document (SED) for an in-depth information resource
  • Consecutive activity, to be launched later a. organizing special sessions in at least one of IABSE symposia or congress b. initiating at least one research project in the scope of TG1.4 with partner task groups
