Cracking of Concrete Buttress Dam Due to Seasonal Temperature Variation

The largest and most important hydropower dams in Sweden are concrete buttress dams. These consist of a large number of concrete monoliths formed by a frontplate with a supporting buttress. Cracks ...

A coupled multi-physics model for creep, shrinkage and fracture of early-age concrete

The behaviour of concrete at early-age is complex and involves several physical fieldssuch as temperature, moisture and deformations. In this paper a hygro-thermo-chemo-mechanicalmodel for the anal ...

Shrinkage cracking of thin irregular shotcrete shells using multiphysics models

Shotcrete (sprayed concrete) is commonly used to support tunnels in good quality hard rock. Including a drainage system often results in end-restrained sections of shotcrete, which have created pro ...
