AZ18,AZ18-10/10,AZ17-700,AZ18-700,AZ19-700 sheet pile

Before analysis can be started, data’s for the sheet pile wall, soil, loads and supports need to be inputted. Earth pressures varies from an initial state referred to as at-rest, Ko to a minimum limit state referred to as active, to a maximum limit state referred to as passive.

Each project starts with the selection of an analysis model and the entry of general details about the project. This makes AZ18 and AZ18 10/10 statically determinate. The classical method of sheet pile design assumes development of active and passive lateral earth pressures. On the menu bar, click AZ18 Project and then choose Model to open the input window. In this window the required analysis models can be selected.

The lateral (horizontal) earth pressure is a function of the soil properties (cohesion, phi angle, and unit weight), height of overburden, and the elevation of the AZ 18 water table Equilibrium analysis of the forces shown in Figure 4-4 allows the active force, or passive force, to be expressed in terms of the geometry and shear strength:Model Select AZ17-700 and AZ18-700 Sheet piling option for analysis of sheet pile. Select the AZ18 10/10 Single pile option for analysis of horizontally loaded piles. These operations result in Wedge methods for soil pressures. Active earth pressure develops when the pile moves or rotates away from the soil allowing the soil to expand laterally (horizontally) in the direction of the pile movement. The coefficient method does not account for the AZ 17-700 and AZ 18-700 ground surface, sloping soil layer boundaries, or the presence of wall/soil adhesion. Active earth pressure is the driving force in AZ 18 10/10 sheet pile stability analysis. With models AZ 18-700 Sheet piling and Single pile you can choose between an Elastic calculation or a none Elastic calculation (i.e. Plastic) of the piling.

When any these effects are present, the steel sheet piling are calculated by a numerical procedure, a wedge method, based on the fundamental assumptions of the Coulomb theory. The single AZ17-700 pile option is only available in combination with the corresponding module. or Select the Diaphragm wall option for AZ 18 and AZ 18 10/10 walls. Elastic calculation. Practical evaluation of soil pressures by the wedge method requires a computer program.

Model window If Plastic is chosen, the Moment - Curvature diagram (M-κ) of the piling will contain 2 branches for AZ 17-700 Sheet piling and 4 branches
for Single pile. In general, a lateral movement of approximately 1 inch is required to fully mobilize the shear resistance for each 20 feet of AZ18-700 wall height. With models Diaphragm AZ19-700 wall, a Plastic analysis is always performed with 4 branches in the Moment - Curvature diagram (M-κ).
