Lateral Analysis 29 4 2019

1. Check the Lateral Analysis in the Pile Design > Design tab. The Lateral Analysis tabs will be visible on the left panel. Design Actions group box will be visible on the top right-corner. 
   

1.   Design Parameters

1. Tolerance: Allowable error of analysed results
   
2. Maximum iteration: Analysis will stop at maximum iteration even though the error is greater than the tolerance. 
   
3. Slope Angle: If the ground is sloping or the pile is raking, please enter the relative angle in degree. 
   
1. Pile rotates anticlockwise with respect to ground surface, the slope angle shall be in positive sign
   
2. Pile rotates clockwise with respect to ground surface, the slope angle shall be in negative sign
   
3. Slope (Ground surface) rotates clockwise with respect to pile, the slope angle shall be in positive sign
   
4. Sloe (Ground surface) rotates anticlockwise with respect to pile, the slope angle shall be in negative sign
   
4. Resistance Side (only applicable if slope angle is not zero): if the soil is in passive on right-hand side of the pile, set this to Front. if the soil is in passive on left-hand side of pile, set this to Back. 
   
5. Loading Type: If this set to static, it indicates that the applied loading is static. If this is set to cyclic, the loading will be applied for number of cycles as defined in Loading Cycle No. 
   
6. Loading Cycle No. (only applicable if Loading Type is set to Cyclic): Number of cycles for the cyclic loading. 
   

2.  Soil Model

1. Soil Model: You can choose various soil models for different type of soil namely, (i) Soft Clay; (ii) Stiff Clay; (iii) Sand; (iv) Void; (v) Linear Elastic (E constant) or (vi) Linear Elastic ("E" Incremental)
   
2.  : Effective soil unit weight
   
3. : Water unit weight
   
4.  Cu : Soil undrained shear strength (can be edited in Soil Materials in Soil Profile tab)
   
5. dCu/Depth: Increment of Undraind Shear Strength against depth
   
6. Ki: Initial soil Stiffness 
   
7. dK/Dept: Increment of soil stiffness against depth
   
8. 
   : Soil Friction angle (can be edited in Soil Materials in Soil Profile tab)
   
   
9. e50: Strain corresponding to one-half the maximum principal stress difference 
   
10. Water Table: Above – water table above this soil layer; Below – Water table below this soil layer
    
11. Depth Interval: Soil layer thickness (can be edited in Soil Materials in Soil Profile tab)
    
12. Depth (Auto calculated): Bottom depth of this soil layer
