Known Issues
The following outlines known issues with the current version ofSTAAD.Pro and suggested workarounds where possible:
| ID | Publishing Notes | WorkAround |
|---|---|---|
| 1199333 | The 2023 User Report module has been updated too include details of all currently available seismic definitions, however, the details of seismic weights included in the definition of self weight, joint weights, member weights, element weights and enclosed zone weights are reported, the details of any Wall Area, Floor Weight and Reference Load case details are currently not included in the report. | No workaround available at this time. |
| 807812 | The cold formed steel design routine used in the BS5950-pt 5 and CSA S136 that process the section properties doe not properly account for the geometry of US Cold formed Angle without lips, British cold formed Z with lips, Butler Zee Purlins, European CHS section and Russian cold formed pipe sections and should not be used with these profiles. | No workaround available at this time. |
| 807595 | The Canadian seismic loading routine NRC 2010 and NRC 2005 does not correctly process the parameters FA and FV, the optional site coefficient parameters for the short and long periods | If it is required to specify these, ie. SCLASS is set to F, then an alternative seismic code should be used. |
| 766112 | The routine that reports section forces on members is not designed to account for the secondary effects resulting from a Direct Analysis. Therefore the intermediate member section results are not valid. | If the forces at required at a specific location along a member, then a node should be inserted into the model at that required location on the member. |
| 635507 | On some computers running Windows 10 version 2004 (10.0.19041), after completing a session in the Steel AutoDrafter or Steel Connection Design Workflow and selecting a different workflow, STAAD.Pro can crash | No workaround available at this time. |
| 541629 | The Windows Account user name of the is currently required to be defined using standard ASCII alphanumeric characters. STAAD.Pro does not support user names which are defined with special or non alphanumeric ASCII characters. | Other than using an alternative computer, there is no workaround available at this time. |
| 532952 | When a model includes a supported node as a control node for control/dependency (previously master/slave), then this is not accounted for in the final statics check and thus can suggest that there is an imbalance from the analysis. | Confirm that the reported allied loading is consistent with the loading applied in the model. |
| 524656 | Where finite elements have been assigned releases that disconnect lateral degrees of freedom, i.e. FX, FY and FZ, do not show the separation of the plate from the node in the displacement diagrams if there is a force which would cause separation, although the analysis results have taken the disconnection into account. | Provide duplicate nodes at the shared location and connect with (control dependant previously master/slave) connections with the required connectivity. |
| 524650 | Assigning a lateral release on the end of a member or finite element, i.e. FX., PY or FZ, the reported intermediate displacements do not account for the separation of the degree of freedom and thus does not correctly display the member displacement. | Use two nodes defined at the same location and connect together with a suitable Control/dependant (previously MASTER/SLAVE) specification. |
| 488517 | The User Report currently does not include the following data Definitions (Load Generators) 1) Snow Load 2) Seismic - Floor weights, reference loads, element weights 3) Pushover definitions 4) Direct Analysis definitions 5) Time History Definition Spectrum, missing mass, cdamp/mdamp option? Loading data 1) Seismic load 2) PMember loading is combined into a general member load 3) Floor Load 4) Snow Load assignment 5) Response Spectra Assignment for code based methods 6) Temperature load - lateral 7) Time History assignment factor and rel/abs | Details of the static seismic load generators should be obtained from a printout of the input file or output file. |
| 488487 | There are currently a number of undocumented OpenSTAAD functions for accessing User Table details in the STAAD model that are displayed when browsing the OpenSTAAD functions. | These are incomplete and should not be used at this time. |
| 488480 | The ISM interoperability does not import/export the coefficient of thermal expansion (alpha) in the correct units. | The details of materials imported from an ISM repository should be checked that the correct unit has been used with the alpha coefficient. |
| 488399 | The Member Query dialog box does not display the forces correctly for load cases analysed with a non linear analysis such as Direct Analysis, P-Delta and GNL where secondary effects need to be considered in establishing the changes of force along the member length. | The member results should be obtained from the Post Processing mode, Beam>Graphs page. |
| 488340 | Mass participation reported for response spectrum loading using SP 14:13300.2011 and SNiP II-7-81 can result in a greater magnitude than that included in the model when RIGID FLOOR DIAPHRAGMS are included. | Avoid the use of RIGID FLOOR DIAPHRAGMS in a model that used the SNiP or SP 14.13330.2011 response spectrum load cases. |
| 488213 | Known Issue. The performance of the torsion design included in the AISC 360-10 design module can cause the design to take a significant amount of time on medium sized to large models. | Workaround is available now to use AISC 360-16 which has a much greater performance. |
| 488029 | The wind loading routine does not account for beta angles on angle profiles | These members should be loaded using a manual method. |
| 487893 | Wind loading on open structures with inclined members assigned with beta angles are not accurately determined. | These members should be loaded using a manual method. |
| 487774 | Known Issue. Currently Node Loads that are defined with the option INCLINED REFJT are processed by the engine such that the vector of the load is defined by the first node in the command. | Only use a single node with each JOINT LOAD, INCLINED REFJT command line. |
| 487754 | Results will be reported for load combinations which have included load cases which are dynamic in nature such as having a response spectrum definition. | Load combinations should not be defined with dynamic load cases. This is not a supported case. |
| 487753 | The use of temperature loading with a geometric non-linear analysis is not supported. | The temperature effects should be replaced with an alternative member or plate load to represent the thermal effect |
| 487697 | For models which have closely modes, a dynamic analysis can produce differences in the individual modal mass participation on some workstations some newer Intel Xeon platform processors. However, the observed variations of the principal analysis results is typically minor. | No workaround at this time |
| 487636 | The option to set the direction of ONEWAY FLOOR load using the parameter TOWARD a given member occasionally fails to direct the load in panels where a beam on a longer edge of the perimeter of the enclosed boundary is shorted than the shorter edge. | If the direction of loading is not displayed as expected, select an alternative member in the floor set. For floors groups defined that encompass multiple enclosed areas, try breaking these into separate floor groups and applying the floor load to each one individually. |
