GGU-UNDERPIN: "Lateral pressures" menu item

If, in addition to the diverse possibilities for determining earth pressure on the wall, you also need to take additional surcharges on the active side into consideration, define them here.

The number of lateral pressures can be modified using the "x lateral pressures to edit" button. Then enter the ordinates in metres from the top of the wall or as absolute heights, and the values for the lateral pressures. When analysing with the new partial safety factors you will also see the "Live" check box because of the differentiation between permanent and changeable lateral pressures.
