Sheet piles AZ20-700,AZ26,AZ24-700,AZ24-700N,AZ26-700N

Select the Sheet piles method for input of the lateral earth pressure ratio: the Ka, K0, Kp basic model the c, phi, delta model (Culmann) the Mixed model to allow selection of the method for each stage and side of the wall, using the AZ20-700 Stages Overview window. Uniform surcharge. A uniform surcharge is assumed to be applied at all points on the soil surface. In general, AZ24-700N lateral movement of approximately 1 inch is required to fully mobilize the shear resistance for each 20 feet of wall height. The Ka, K0, Kp method gives constant earth pressure coefficients over a soil layer, whilst the Culmann method allows them to vary. Passive earth pressure for AZ20-700 and AZ26 develops when the pile moves or rotate towards the soil, tending to compress the soil laterally (horizontally) in the direction of the pile movement.

The effect of the steel sheet pile uniform surcharge is to increase the effective vertical soil pressure, pv in Equations 4-7 and 4-8, by an amount equal to the magnitude of the surcharge. The Culmann method also allows calculation for non-horizontal surfaces and non-uniform loads. Strips loads. A strip load is continuous parallel to the longitudinal axis of the wall but is of finite extent perpendicular to the AZ 24-700N,AZ 26-700N wall. Mark the Verification (EC7/CUR) check-box to enable the special calculation functions for sheet piling and diaphragm wall design according to the Eurocode 7 and the CUR 166 model guidelines. Passive AZ 20-700 earth pressure is the resisting force in sheet pile stability analysis. The c, phi, delta model is only available in combination with the corresponding module. Options Mark the Check vertical balance check-box to perform a vertical balance check. In general, a lateral movement of approximately 1 inch is required to fully mobilize the shear resistance for each 2 feet of AZ 24-700N wall height.

The additional pressure on the AZ24-700 and AZ24-700N wall is given by the equations. Any negative pressures calculated for strips loads are to be ignored. This option is only available in combination with the corresponding module. Line loads. A continuous load parallel to the AZ26 wall but of narrow dimension perpendicular to the wall may be treated as a line load as shown in Figure 4-6. On the menu bar, click Project and then choose User Defined Partial Factors. This AZ 26 option is only available if the Verification (EC7/CUR) option has be selected in the Model window. More rigorous analysis may be conducted, assuming that the AZ26-700N soil behaves as a spring, with the maximum resistance equal to the active or passive lateral earth pressure, as appropriate.

In this window the user-defined partial factors used for the AZ 26 and AZ 24-700 design according to the following standard can be defined:
A ramp load, increases AZ26-700N linearly from zero to a maximum which subsequently remains uniform away from the AZ 20-700 wall. Single pile Select the type of pile loading: forces or soil displacements. In case of AZ24-700 pile loaded by soil displacements, the soil displacements can be either user input or automatically calculated using De Leeuw tables.The AZ 26-700N load is assumed to be continuous parallel to the wall. The equation for lateral pressure is given by the equation in Mark the Settlement by vibration check-box to calculate the surface settlements during the installation of AZ 24-700 sheet piling by vibration.
