Usually, there are shear keys in the mat foundations due to the volume to be poured and to minimize the thermal effects. There are typical dimensions for keys to provided to carry the shear forces in the foundations. Generally, we do not design the shear keys as the are very stiff and they can carry the applied loads. The … See more The key purpose of the shear key is to maintain the integrity of the structure. In general, we do not transfer the bending moment through the shear key though we allowed transferring … See more They are classified based on the type of the structure, nature of construction, magnitude of the applied loads, etc. Though design for the shape of the key is not done, the typical values specified in the detailing manuals … See more Generally, we provide construction jointsjust above the base.
