CYCLIC LATERAL LOADING OF A MODEL PILE GROUP IN CLAY SOIL. EXECUTIVE SUMMARY. PHASE 2C
In certain regions of the world, designing deep foundations to withstand seismic loading is a reality. Seismic loading of structures and foundations reaches its most critical state as a cyclic lateral force. The response of soils and foundations to repetitive lateral forces is highly complex, relegating most design methods to be based on overly conservative rules of-thumb. The primary objective of this research was to analyze mechanics of seismic loading on pile groups in clay soils. To achieve this, a model testing facility was constructed to house a fully instrumented 1x5 model pile group that was subjected to cyclic lateral loading. An empirically based method for pile group design is suggested based on results generated from model pile group testing.
