Analysis
In the "Data entry" tab, in the "Analysis" group of the main toolbar, the options required for checking compliance, designing the geometry and reinforcement and analysing the results of each phase are available.
The analysis model used to obtain the forces and displacements of the embedded wall is based on the soil-embedded wall interaction methods, where the magnitude of the soil pressures on the embedded wall depends on the displacement of the embedded wall. For the analysis of the loads and/or reaction produced by the soil on the embedded wall, it is considered to have a law of (non-linear) elastoplastic behaviour that is obtained from the approximation of the real behaviour of the soil, including its plasticisation. The linear range of behaviour is associated with the concept of the lateral subgrade modulus of the soil, and the plastic range with the concept of active or passive soil pressure depending on the direction of displacement. Likewise, the support elements (anchors, struts and floor slabs) enter a series of additional constraints and loads, that are considered at the heights at which they are located.
Since the solution of the problem depends on the deformation of the embedded wall, the method requires an iterative process until the equilibrium situation at iteration "i" is close enough to that obtained at iteration "i+1".
The options available are:
- Phase results:
Draws graphs related to the selected phase on a graduated grid on the screen. - Force diagrams:
Allows users to consult the graphs of the results for the selected phase. - Graphs for soil behaviour:
Allows users to check the graphs of the soil's behaviour in the different phases. - Critical slip circle:
Analyses and draws the critical slip circle on screen. At the same time, the contour plot map of safety coefficients is drawn on the position of all the analysed slip circles. - Check:
Checks compliance with all requirements for a given geometry and reinforcement or analysed by means of a pre-design. This option does not redesign the reinforcement provided. - Design geometry:
Designs the geometry of the wall. - Design all:
Designs the geometry of the wall for the subsequent design of the reinforcement. After the design, a check is automatically carried out.
