Tutorial : Structure with Foundation on Soil (Elastic, 3D Elements)

Tutorial : Structure with Foundation on Soil (Elastic, 3D Elements)


Select Opensees problemtype Enter point coordinates Connect lines to points Create surfaces from lines Create volumes by extruding the upper surfaces along z axis Copying the initial volumes along x axis Extrude the upper side surface along x axis to create the corresponding beam Continue copying volumes (along y axis) And by extruding the corresponding surfaces along y axis the rest beams are created Select ‘flat’ render mode in order to change the model visualization Create more lines to define surfaces from which the ‘soil’ volumes will be created Create these surfaces Create ‘soil’ volumes by extruding surfaces along z axis and extrude the ‘soil’ volumes along x and y axis Select ‘flat’ render mode in order to change the model visualization Create concrete and soil materials Create concrete and soil elements Set analysis properties (3 dimensions , 3 degrees of Freedom)
Create concrete and soil elements Set analysis properties (3 dimensions , 3 degrees of Freedom) Assign concrete Element to the corresponding volumes Create volumes for the foundations Assign concrete element to the foundation volumes Assign soil element to the ‘soil’ volumes Inspect concrete and soil assignments Assign restraints (fixes) at the base and side surfaces Assign point loads Inspect the point loads Set meshing element type for the volumes (hexahedra) … and mesh the volumes Collapse model in order to merge double nodes Save model Run OpenSees Analysis Analysis complete, go to postprocess View deformed shape (and change the scale factor of deformations)
View deformed shape (and change the scale factor of deformations) Deformation contours (in x axis) … in y axis … in z axis and total displacements Contour lines for total displacements Maximum deformation Deformation vectors Thanks for watching !

  1. Hi, I can not install GiD opensees. I downloaded the .exe file but it does not run
