Now you defined your beam element and need to add truss element as well. 6.įigure 8: Modify BEAM188 element type options. In Element Types window, select BEAM188 element and then pick Options… to modify your BEAM188 element type options, as in Figure 8. Select (Structural) Beam and 2 node 188 (that is, BEAM188), OK. In Element Types, seen in Figure 7, pick Add → Library of Element Types. Main Menu → Preprocessor → Element Type → Add/Edit/Delete, as in Figure 7. Check Structural, accept default h-Method, OK, as in Figure 6.įigure 6: Declare the selection of a structural analysis. Main Menu → Preferences → Preferences for GUI Filtering. Open and add to element types you need: 1.

Change Title, enter a descriptive title, OK (see Figure 5).ģ.2 Element type data You will need a 3D structural line element, or frame member, that transmits axial forces, axial torsion, and transverse bending moments and also 3D structural link element for your truss members.

To keep up with your analysis studies over time create descriptive titles: 1. Browse for Folder → Change Working Directory, pick your directory (ANSYS Tutorial_P5-70 in Figure 4), OK.įigure 4: Establish a directory for the analysis files. The ANSYS file sizes for real engineering problems get to be quite large, so have a directory dedicated to ANSYS: 1. Change_Jobname, type in the new name, OK (as seen in Figure 3). If you think that has occurred hit the Raise Hidden button,ġ. įigure 2: Opening ANSYS to the Utility Menu and graphics window.ģ Preprocessing: Defining the Problem 3.1 Select job name and analysis type The various menus below will sometimes get moved to a back (hidden) window. That will bring you to the main ANSYS Utility Menu as seen in Figure 2.

Choose a scaling factor for the elastic displacements such that they are appreciable in the plot. An ANSYS plot of the undeformed and the deformed space frame. 1.1 Deliverables: From your simulation results, provide: 1. Material properties can be located inside the back cover of the textbook. Using Appendix F (pages #882-907), you can choose from the wide flange sections listed for the beam elements (one size used for all beams), the rectangular hollow structural sections (HSS) for the vertical columns (one size used for all columns) and the pipe sections for the corner bracing (one size used for all braces). When calculating the threshold for buckling you can use Euler’s buckling formula (which assumes pinned-pinned conditions). You can assume that all joints are welded except the corner braces which are connected to the columns and beams with idealized spherical joints. have corner braces that are well removed from the possibility of yield and buckling due to internal compression (using a FOS of 5.0). have vertical columns that are well removed from the possibility of yield and buckling due to internal compression (using a FOS of 5.0). have a beam structure at the top that is well removed from the possibility of material yield due to bending (using a FOS of 5.0), and 3.
