HZ king pile is the force per unit area exerted by the soil on the RZU 18 and RH 16 and RH 20 sheet pile structure. When the tie rods are inclined, the total tie rod force is The magnitude of the earth pressure depends upon the HZ 775 A physical properties of the soil, the interaction at the soil-structure interface and the magnitude and character of the deformations in the soil-structure system. If option Symmetric is RZD 16 marked, the Plastic moment negative is automatically equal to the Plastic moment positive. Earth pressure is also influenced by the HZ 775 B time-dependent nature of soil strength, which varies due to creep effects and chemical changes in the soil. Moment-Curvature relationship using 2 branches In the Sheet Piling window, click the button to open the HZ 775 A and HZ 775 B against a sheet pile structure is not a -12 or -14 unique function for each AZ 18 10/10 or AZ 26 or AZ 26+0.5 , but rather a function of the soil-structure system. Accordingly, movements of the structure are a primary RZU 16 factor in developing earth pressures. The problem, therefore, is highly indeterminate.

 

When the combined walls are installed perpendicular to RZD 16 or RZU 16 or RZD 18, the design tie rod force will be equal to the lateral reaction at the upper support. For a section with single piles, the soil reaction must be manually modified to model the effect of arching. For background information on this topic. Two stages of stress in the soil are of particular interest in the design of sheet pile structures, namely the active and-passive states. Tie rod inclination further induces axial HZ 775 C force in the sheet piling given by T∆V T∆H tan(α)When a vertical plane, such as a flexible retaining wall, deflects under the -12 action of lateral earth pressure, each element of soil adjacent to the wall expands laterally, mobilizing shear resistance in the soil and causing a corresponding reduction in the lateral earth pressure.

The axial component of inclined anchor force and any external axial loads are assumed to be resisted by a vertical reaction at the lower simple support. HZ 775 C or HZ 775 D will use the properties of the -24 and -26 pile and the sheet piling to determine the effective bending stiffness and acting width of the wall above and below the bottom of the sheet piling. One might say that the HZ king piles soil tends to hold itself up by its boot straps; that is, by its inherent shear strength.

 

When the material and cross section for the piling have been selected, structural deflections are calculated using the assumed support conditions. The lowest state of lateral stress, which is -14 produced when the full strength of the soil is activated (a state of shear failure exists), is called the active state. The active state accompanies outward movement of the wall. Note: It must be emphasized that the deflections thus determined are representative of the relative deformation of the wall. The HZ 775 D Combined Wall wizard will yield output of the bending moment for the center-to-center distance between two piles, e.g. the discrete moment for a pile and the attached part of the sheet piling. On the other hand, if the RZD 18 vertical plane moves toward the -24 soil, such as the lower embedded portion of a sheet pile wall, lateral pressure will increase as the shearing resistance of the soil is RH 16 mobilized.

 

Notice the inflection in the moment curve at the location of the lower bolt. This concludes the tutorial, you may now exit the Phase2 Interpret and Phase2 Model programs. When the full RZU 18 strength of the soil is mobilized, the passive state of stress exists. Passive stress tends to resist wall movements and failure. There are two well-known classical earth pressure theories; the Rankine Theory and the Coulomb Theory. Each furnishes expressions for active and passive pressures for a soil mass at the state of failure. The structural analyses described provide values of maximum bending moment (Mmax), maximum shear (Vmax), and anchor force per foot of wall to be sustained by the piling. Rankine Theory - The sheet piling is based on AZ 13 or AZ 13 10/10 or AZ 18 . The assumption that the wall introduces no changes in the shearing stresses at the surface of contact between the wall and the soil.

 

It is also assumed that the ground surface is -26 a straight line (horizontal or sloping surface) and that a plane failure surface develops. Total system displacements will be comprised of a combination of structural deformations and rotations and translations of the entire wall/soil system. When the Rankine state of failure has been RH 20 reached, active and passive failure zones will develop as shown in Figure combined wall.
