The results on the side of the section cut that includes the fixed end will represent the beam reactions, while the results on the side of the section cut that includes the free joint will be zero. As an example, consider a section cut located in the middle of a cantilever beam modeled by a single frame element and loaded by its self-weight only.

Globally, these forces are in equilibrium, but their relation to a section cut is arbitrary and does not necessarily serve the function and conditions of a free-body diagram. Section cuts defined using the graphical user interfaceįor section cuts defined using the graphical user interface, frequently asked questions are as follows: Why is the magnitude of integrated forces different for the left and right sides?Įxpanded Question: According to equilibrium, should not the magnitude of integrated forces be equivalent for both left and right sides?Īnswer: Section-cut forces may be different on either side of a section cut because they are based on joint forces which occur in the global system. are on the specified side of the cutting plane. are assigned to objects entirely within the cutting plane and 3). Joints considered include those which 1). For section cuts defined by a quadrilateral cutting plane, SAP2000 calculates section-cut forces by summing the joint forces within frame, shell, and link objects which are entirely within the cutting plane and included in the section-cut group.

Can the cutting plane be defined through any joints?Īnswer: If possible, the cutting plane should not pass directly through joints such that the software may determine the side of the cutting plane on which joints are located. Discretization should be refined to adequately define section cuts.įor section cuts defined by a cutting plane, frequently asked questions are as follows: What is the orientation of the positive 3 axis for quadrilateral elements?Īnswer: The positive 3 axis of quadrilateral elements follows the same convention as that for shell objects in which axis orientation is normal to the element area, and positive projection follows the cross product of axes 1 and 2. Macros, basic programming, or the Application Programming Interface (API) may help expedite this process. Export data to Excel for post-processing and plotting of shear and moment diagrams.Run the analysis, then display section-cut forces in tabular format by selecting Display > Show Tables > Analysis Results > Structure Output > Other Output Items > Section Cuts > Table: Section Cut Forces - Analysis.

Data may also be imported from Excel, where section-cut data may be automated over a series of intervals. Can I view the shear and bending-moment diagrams for this series of section cuts?Īnswer: This series of diagrams may be obtained with additional pre-processing and post-processing, described as follows:ĭefine multiple section cuts using interactive database editing, available through Edit > Interactive Database Editing. Directly define section cuts through Advanced > Define > Define > Section Cuts.Ĭan force diagrams be displayed for a sequence of section cuts?Įxtended Question: I have made and saved section cuts along the length of a bridge slab.Display frame forces within the 2D global view, draw the section cut, then save.

How is this resolved?Īnswer: Two options are available for saving drawn section cuts. Currently only cuts in undeformed 2D Global views can be saved. How do I save a drawn section cut?Įxtended Question: When I try to save a section cut, I receive an error message which reads: Section Cut cannot be saved. Frame shear force will correspond to the section-cut force in the 1 direction. Display the elevation view of the framing of interest, display the frame force to be reported, then draw a section cut at any elevation within the story by selecting Draw > Section Cut. How are story forces and story shears reported for each braced frame?Īnswer: This can be done using section cuts. General frequently asked questions which concern section cuts are as follows: How are story forces and story shears reported?Įxtended Question: I am running a seismic analysis on a multi-story braced-frame project with rigid diaphragms.
