i need an engineer with midas gts nx experience to study foundation settlement for both piled foundation and raft foundation. carry out an assessment of existing piled foundation for a building that i. Similarly at node 20 and 5, spring coefficient corresponding to the area 0.5m2 and 0.25m2 respectively, has to be entered. If the geotechnical boundary conditions are to be entered only for a small number of nodes, you can enter as above, taking into account the contribution of each sectional area. However, if the nodes you need to enter the geotechnical boundary conditions are multiple in number, it can become a very cumbersome task. Surface Spring Supports function of midas Civil is a feature to enter the soil boundary conditions which automatically calculates spring coefficient based on the shared sectional area. By this way you can automatically enter a number of boundary conditions of the ground at once. Surface Spring Supports feature is available both for the line-element model and plate / three-dimensional elements model.

For Plate elements / three-dimensional element mode, the shared area of the selected nodes are automatically considered in the spring coefficient calculation, and for the line element it is calculated by considering the Shared length × Width entered. Therefore, the user to enter the geotechnical boundary conditions in the model, must be using the Surface Spring Supports.
