Deep Underground Science and Engineering, EarlyView.Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...
