The design of a block foundation as well as a bucket foundation with smooth bucket sides is performed by analyzing the horizontal components Ho and Hu.
In this case, the restraining moment at the column base is converted into a horizontal component on the upper side (Ho) and on the bottom side (Hu).
For block and bucket foundations with smooth bucket sides, no vertical component is calculated to be used for the design of anchorage.
See Image 01 and Image 02.
The situation is different for block and bucket foundations with rough bucket sides. In this case, you can activate the design of the lap length of bucket reinforcement in Details.
