Toward identifying the ASR-induced stresses from displacement measurements and crack observations—Demonstration on a beam bridge in Norway

Alkali–silica reaction (ASR) in concrete causes expansion and degradation of the material, which might give adverse structural consequences. From the structural engineer point view, the greatest concern is if ASR leads to loss of structural integrity. Two natural questions arise when assessing existing concrete structures affected by ASR: (1)...

Load effects in reinforced concrete beam bridges affected by alkali–silica reaction—Constitutive modelling including expansion, cracking, creep and crushing

Material modelling, from the micro to the macro level, of concrete affected by alkali–silica reaction (ASR) has been devoted a lot of research. However, the application of the material models in structural analyses of reinforced concrete (RC) structures, showing the structural implications/consequences of ASR, has got little attention in the...

Skewed slab highway bridges: A parametric study on the design of reinforced concrete, simply supported skewed slab highway bridges

In situations with spatial limitations where a bridge is desired, a skewed bridge is a solution. The bridge deck of a skewed bridge has the shape of a parallelogram, in which the angle that remains in the acute corners is defined as the skew angle. This thesis focuses on the design of reinforced concrete skewed slab highway bridges that are...

A Study of the Application of Safety Formats in Non-linear Finite Element Analysis of Reinforced Concrete Tunnel Segment

The application of non-linear finite element analysis is important nowadays to simulate the real behavior of structure. A sort of non-linear finite element analysis with and without safety formats referring to Model Code 2010 is applied in this thesis, to study the FEM simulation of the shear capacity of reinforced concrete structure. A case...
