WebPerforming a parametric study, Seed and Whitman (1970) noted that the total dynamic lateral earth pressure (Pae) could be divided into two separate ingredients: initial static pressure (Pa) and the dynamic increment due to the seismic loading (ΞPae): πππ = ππ + π₯πππ (4) Therefore: πΎππ = πΎπ + π₯πΎππ (5) Where Kae is the total dynamic coefficient of β¦ Weband 40Β° with an increment of 5Β° and the results are shown in Fig. 4. Note that contours of constant roughness coefficients, C,, are also drawn in Fig. 4 for ease of application.
