Concrete cracking is a significant and on-going concern in our industry. A combination of factors such as drying shrinkage, thermal contraction and subgrade settlement (and many more factors) contribute to the issue. This technical evening looks at the impact of cracking in the industry and how it is being managed in a variety of situations.

Topic - Cracking in Concrete: A Structural Engineer's Perspective
Compared to structural steel, concrete has some difficult properties, not least that it cracks in tension. Structural engineers are ambivalent about how to deal with concrete’s lack of reliability in tension and have to recognise that there are good cracks and bad cracks.  Good cracks are those that relieve unwanted tensions and are only a durability problem – they  can be satisfactorily be dealt with. Bad cracks are those which are a sign of structural problems, and need to be dealt with urgently.
