A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. The estimation of a fatigue crack life using the linear elastic fracture mechanics (LEFM) theory involves the calculation of stress intensity factors (S ...

Prediction of fatigue life of reinforced concrete bridges using Fracture Mechanics

Eugen Brühwiler, Marina Rocha Pinto Portela Nunes

With the occurrence of higher and more frequent axle loads, bridges are more solicited by fatigue loading. Bridge elements like deck slabs are subjected to a high number of stress cycles at relatively small stress magnitudes. The application of Fracture Me ...

Discontinuous Galerkin finite element heterogeneous multiscale method for elliptic problems with multiple scales

Assyr Abdulle

An analysis of a multiscale symmetric interior penalty discontinuous Galerkin finite element method for the numerical discretization of elliptic problems with multiple scales is proposed. This new method, first described in [A. Abdulle, C.R. Acad. Sci. Par ...

Fatigue Testing and Analysis of an Orthotropic Bridge Welded Detail Using Structural Hot Spot Stress Method

Farshid Zamiri Akhlaghi

At present, more powerful tools for numerical modelling and structural analysis are available for the use in fatigue design and assessment of complex structures. Taking advantage of these tools, structural hot spot stress approach (SHSS) can predict the fa ...

Extension of the Uniform Material Law for High Strength Steels

Sinan Korkmaz

Uniform Material Law (UML) is a handy and user-friendly method since only the tensile strength data of the material is needed for estimation of the strain-life curve, in contrast to other methods, such as four-point correlation method, universal slopes met ...
