Analysis

The frame "Analysis" displays the analysis results. Switching to this regime automatically runs the analysis. The frame contains three buttons to show the analysis results:

  • Kh + pressures
Variation of the modulus of subsoil reaction is displayed in the left part of the desktop (by default a blue color with hatching) is assumed. Referring to the method of depending pressures some of the springs (values of modules of subsoil reaction) are removed (spring stiffness set equal to zero) from the analysis. The analysis may fail to converge providing the critical (limit) state developed both in front and behind the structure and there is not enough constrains available (anchors, supports). The program exists without finding a solution. An error message appears in the bottom part of the frame – such a case calls for modification in problem input – e.g., add an anchor, change a depth of excavation, improve soil parameters, etc.
Some construction stages display (by default a yellow dotted line is assumed) deformation at the onset of mobilization of the earth pressure at rest – this is a complementary information showing plastic deformation of a structure.
Distributions of limiting pressures (by default a green dashed line is assumed) are presented in the right part of the window (passive pressure, pressure at rest and active pressure). The actual pressure acting on a structure is plotted in a solid blue line.
Both deformed (by default a solid red color is assumed) and undeformed structure appears in the right part of the desktop. Forces and displacements developed in anchors, supports and props are also shown.
  • Internal forces
Plot of a structure together with forces acting in anchors, reactions and deformations of supports and props appear in the left part of the desktop. Distributions of bending moment and shear force are then plotted on the right.
  • Deformations + Stresses
Plot of a structure together with forces acting in anchors, reactions and deformations of supports and props appear in the left part of the desktop. The deformed shape of a structure together with overall pressure acting on a structure is then plotted on the right.

Providing the modulus of subsoil reaction is found by iteration it is necessary to check the course of iteration in the dialog window. Details are provided in the theoretical part of the hint "Modulus of subsoil reaction determined by iteration".
