PSEUDO-STATIC THRUST ON CANTILEVER WALLS

 VENANZIO R. GRECO

ABSTRACT This technical note extends the application field of the method proposed by the author (Greco, 1999) to walls subject to seismic conditions analyzed by the pseudo-static method of Mononobe and Okabe. The active thrust is calculated maximizing its horizontal component (or minimizing its vertical one) with respect to the inclination angles of the planes bounding the thrust wedge. This also corresponds to minimizing the safety factor against sliding along the base. Cantilever walls with both elongated and short heels are studied in this note.
