By using elements with directly inputted stiffness to represent the ground, fixed ends are placed underneath. using material properties and cross-section, the Elastic Link directly inputs the calculated stiffness. While a beam element calculates axial stiffness (EA), flexural stiffness (EI), etc. When inputting boundary conditions in midas Civil, which take into account the stiffness of the soil, the most commonly used functions are 'Point Spring Supports' and 'Elastic Link'.įirst, the Elastic Link is similar to a beam element.
Underground structures are put on the ground, and the soil underneath can both support and be sinking under the loads of the structure. How do you input the boundary conditions for underground structures?
