New-Concrete Society Technical Report 67:

This Article discuses the types of movement, restrain and cracking in concrete structures.It acknowledges the loading bearing nature of concrete, but focuses more on other factors such as temperature, early-aged construction, humidity effects, creep and long term shrinkage. They say it important to understand the difference between the type movement and the source of movement, as it usually caused by multiple sources. It also discuses the importance the restraint to minimize movement. This can be done in several ways reinforcement, temperature differentials at interfaces.
