ABSTRACT: The paper studies the behavior of reinforced concrete raft foundations for
multi-story buildings. It also develops a reliability assessment tool for multi-
story building raft foundations subjected to earthquake loading. Several
multi-story buildings with various configurations, heights, and soil profiles,
were subjected to several ACI code combinations of gravity and earthquake
loads from different seismic zones. The reliability of the raft foundations of
these buildings was assessed using the reliability index approach based on
their resistance to the applied loads. Also, the responses of the multi-story
buildings under these loading combinations were studied and analyzed in order
to draw recommendations and guidelines for the preliminary design of
structurally efficient and reliable raft foundations in earthquake zones.
