Results - Finite Element Model Information
Following an analysis you can select
to display the finite element model that is created for each story of the analysis.Refer to the manual for information regarding the Finite Element model created for each story.
Each story in the structure is analyzed independently. You can use this dialog box to view the model that was analyzed on each story. If the analysis reported an error, it will report a member number, node number or a coordinate. You can use this dialog box to view the story that was being analyzed when the error occurred, so that the location of the error might be observed and action taken to correct the problem.
Click Apply to have the selected options display on the screen.
Setting | Description | ||||||
---|---|---|---|---|---|---|---|
Story | Select the Story for which to display the Finite Element Model that was analyzed. When the Apply button is clicked, only the members that were part of the analysis of this story will be displayed. | ||||||
Mesh | Select this option to display the finite element mesh of the selected story. A quadrilateral element mesh is automatically generated using the criteria specified in the mesh controls. The mesh is always generated for the story at which there are any two way slab-decks. The slab deck mesh is not generated for stories which have only one way slab deck. A slab-deck may have one or more openings defined in the layout. The meshing procedure considers columns as point constraints, beams and walls (above and below) as line constraints and hence always a conformal mesh is generated. | ||||||
Beam Fixity | Select this option to display the fixities that are assigned to each physical member for the analysis. The fixities assigned may differ from those observed using the View - Members window as they are modified according to the following: Gravity beams in general are all considered released (pinned) about the major and minor axis at each end, but fixed for torsion. However, gravity (concrete and material 'other') beams can have fixity assigned in RAM Concrete Analysis or in RAM Modeler. Frame beams all utilize the fixity they were assigned by the user in the RAM Modeler or RAM Frame. If instability occurs at nodes of frame members their fixity may need to be modified in the RAM Modeler or RAM Frame. |
||||||
Column Fixity | Select this option to display the fixities that are assigned to each physical column for the analysis. The fixities assigned may differ from those observed using the View - Members window as they are modified according to the following: Gravity columns are assumed continuous above and below the story being analyzed. However, the gravity (non-concrete) columns above the story are assumed pinned (released) at the level of the story being analyzed. Concrete gravity columns are continuous through the story being analyzed. The user can choose to release the base of gravity columns where they frame into the foundation (refer to Criteria Analysis). Frame columns all utilize the fixity they were assigned by the user in RAM Modeler or RAM Frame. |
||||||
FE Nodes | The physical model created in the RAM Modeler is automatically converted to create a finite element model for the analysis. At each location that a member is intersected by any other members it is given a node. By selecting this option all the nodes for the selected story's finite element model will be displayed. Note that there may be many nodes displayed interior to slab decks and walls. These nodes represent the locations at which the slab deck and wall has been meshed. A size slider is provided to change the size of the nodes during the display of the finite element model.
