Description:
This webinar focuses on finite element thermal-structural coupled analysis to evaluate the thermal behaviour and mechanical response of concrete structures. It includes two application examples, risk of early-age thermal cracking and fire safety assessment of tunnel linings along with tips and comparisons with published data or test results.
These examples demonstrate the use of finite element analysis in engineering practice to evaluate thermal dynamics (temperatures and associatedstresses) in concrete structures, applicable to both new design and forensic engineering scenarios.
- Assessment of the risk of early-age thermal cracking due to concrete maturing heat and ambient temperature,
considering heat transfer with combined emission and absorption, and induced thermal stresses combined with structural loads. - Fire safety assessment of tunnel linings using transient thermal-structural coupled analysis according to
Eurocodes EN 1992-1-2 [1] and EN 1993-1-2 [2].
For accurate results, the analysis considers concrete’s nonlinear thermal and time-dependent material properties, as well as induced thermal stresses and their combined effects with other mechanical loads.
About CivilFEM powered by Marc
CivilFEM powered by Marc has been developed leveraging one of the world’s most robust mechanical software, Marc from Hexagon. This fusion has resulted in a high-end, general-purpose finite element software tailored for civil, structural, and geotechnical engineering applications. It is suitable for performing advanced analyses across all construction and civil/structural sectors.
Its unique features encompass the checking and design of civil structures in accordance with the most important codes and standards, incorporating all nonlinearities with high accuracy and low computational cost. This reduces processing time and aids in achieving convergence in complex models.
CivilFEM’s thermal-structural coupling capability allows for detailed advanced heat transfer analysis, encompassing the calculation of temperature distribution (steady-state or transient) and induced thermal stresses, alongside their combined effects with other mechanical loads on structural behavior. This covers a wide range of civil engineering needs, including early-age thermal cracking in concrete due to heat of hydration, effects of ambient temperature, solar radiation, or fire protection.
Key features include:
- Definition of material thermal properties (thermal conductivity and specific heat) with linear and nonlinear behavior (temperature-dependent properties).
- Thermal orthotropic material properties.
- Convective and conductive boundary conditions applicable to any type of elements.
- Non-linear steady-state or transient analyses.
- Postprocessing capabilities for heat transfer analysis, including temperature, thermal flux, and thermal gradients with vector plots.
- Options for conducting steady-state/static or transient thermal-structural coupled analyses.
