PSEUDO-STATIC ANALYSIS FOR EARTH THRUST COMPUTATIONS

The active thrust on retaining walls in seismic conditions can be evaluated using the method of Mononobe and Okabe. In this approach, Arango proposed considering a modified thrust wedge, in order to use the analytical solution obtained by MuellerBreslau. The same result can be achieved, in a more general and simple form, by modifying the shear strength angle of the soil, the friction angle between soil and wall and the soil unit weight.
