Raft Foundation — Design Requirements and Applicability
When raft foundation is founded on sand, differential settlement governs the design but this is determined by the strength and stiffness of the raft structure and is very difficult to assess. Accurate estimations of all types of loads, moments, and forces are needed for the present as well as for future expansion.
