Surcharges

The frame "Surcharges" contains a table with the list of surcharges. Adding (editing) surcharges is performed in the "New surcharges" dialog window ("Adjust surcharge properties"). The inputted surcharges can also be edited on the desktop with the help of active objects. The program employs the following coordinate systems.

All inputted parameters of the surcharge can be modified in the stage of construction, in which the surcharge was introduced. In subsequent stages it is only possible to modify its magnitude (option "Adjust magnitude").

This frame serves to introduce surcharges applied only to the soil body. The surcharge applied to a beam element is introduced in the frame – beam load.

An arbitrary number of surcharges can be specified in individual stages. The surcharge may act either on the existing interface (including ground surface) or can be applied anywhere in the soil body.

In subsequent stages we are free to either remove the inputted surcharge or to modify its magnitude.

Note that applying the surcharge directly on the ground surface may lead to excessive plastic deformations in the vicinity of the surcharge and the analysis may fail to converge. In such a case, one may either place a beam element under the applied surcharge, or to choose an elastic or modified elastic material model for the soil below the surcharge.
