The seismic effects are generally considered as pseudo-static forces to be added to the other static forces. A detailed review ofthe literature regarding the computation of passive earth pressure using planar failure, composite failure mechanism and experimental investigations are presented in the following sections. In addition, the review of the literature for the computation of earthquake-induced displacements is also presented. [Pg.44]

The conventional method for the calculation of seismic passive earth pressure is the Mononobe and Okabe method (Kramer, 2003). Morrison and Ebeling (1995) reported that the Mononobe and Okabe equation assumes a planar failme surface, which is not the most critical mode of failure for determining the passive failure load. Soubra(2000), Kumar(2001), SoubraandMacuh (2002) and SubbaRao and Choudhuiy (2005) used... [Pg.44]

The seismic passive earth pressure ((t)) can be obtained by resolving the forces on portions, H GJ and H NJ horizontally and vertically (Refer free body diagram shown in Figure 3), and considering the equilibrium of the forces and hence it can be expressed as follows ... [Pg.49]

The results presented in Tables 3, 4 and 5 shows the effect of horizontal seismic acceleration coefficient (fc ) and vertical seismic acceleration coefficient k ) (expressed in terms of fc as 0, 0.5 k and k )on the magnitude of seismic passive earth pressure. It can be noted that as the magnitudes of fc and / k ratio increase, seismic... [Pg.56]
