Contraction joints (sometimes called control joints) are used in unreinforced and lightly reinforced slabs-on-ground to minimize random cracking. By creating straight-line weakened-planes in concrete, ...

In the dome of the Pantheon in Rome, several construction techniques were used to allow such a bold construction to stand. One concerns the composition of the concrete (in this case, non-reinforced ...

Two new developments have recently occurred regarding the installation of contraction joints in slabs-on-ground. First, the ACI Committee on Residential Concrete now recognizes joints, installed soon ...

This study experimentally investigates the structural behavior of steel–concrete composite slabs under monotonic loading, with a focus on evaluating the influence of fiber content, fiber types, layer ...
