Surcharge
The "Surcharge" frame contains a table with a list of input surcharges. Adding (editing) surcharge is performed in the "New surcharge" dialog window. The input surcharges can be edited on the desktop with the help of active dimensions or by active objects.
The z-coordinate measured from the top point of a structure is specified (positive direction downwards) when inputting the surcharge at a certain depth. In case when the surcharge is found out of the terrain the program prompts an error message before calculation.
Either permanent, variable, or accidental surcharge can be specified. Selecting the particular type of surcharge also renders the corresponding design coefficient to multiply the resulting load action. Accidental surcharge with a favorable effect is not considered in the analysis.
Analysis of earth pressures due to surcharges is described in the theoretical part of the help, chapter "Influence of surcharge".
