Analysis of walls

Verification analysis of walls can be performed with the help of:

• theory of limit states
• factor of safety

In addition, the bearing capacity of foundation soil is examined for both cases.

Following forces are used in the verification:

• weight of wall – depends on the shape and unit weight of wall (for input use the "Material" dialogue window) – uplift pressure is introduced for walls found below the groundwater table
• resistance on front face – when inputting the resistance on front face the corresponding force acts as the pressure at rest, or passive pressure or reduced passive pressure
• gravity forces of earth wedges – an arbitrary number of these forces may occur depending on the shape of structure
• active earth pressure or pressure at rest acting on the structure – the basic loading of structure due earth pressures - depending on the selected option in the frame "Settings" the pressure is computed either with or without reduction of input soil parameters
• forces due to water effects or pore pressure, respectively
• forces due to surcharge – a single force corresponds to each inputted surcharge. If the magnitude of force due to surcharge is equal to zero (the surcharge has no effect on a structure) then it does not appear in the picture but only in the table listing
• inputted forces – forces entering the analysis are displayed
• forces due to earthquake – several forces enter the analysis due to earthquake – increase of earth pressure acting on a structure, reduction of passive pressure on the front face of a structure, or force due to free water behind structure
• mesh step joints and reinforcements are displayed and included providing they appear in the analysis

• base anchorage of wall
