    Need Help in STAAD Foundation

    From within the software help go to Verification Manual and refer to section 5 which contain details of how the different values are calculated for the ACI code. If you still have questions, please reach out to Bentley technical support.

    STAAD Compression Springs Issue

    Few suggestions: Make sure you are using REPEAT LOADs to combine load cases and not LOAD COMB. This is essential since you are using compression only springs. Make sure you are including both gravity and lateral loads in cases that you are interested in. Connectivity between beam elements and...

    STAAD Triangular Plate Stresses

    Yes aspect ratio 1:1 is ideal. We should try not to exceed 4:1.

    STAAD Triangular Plate Stresses

    As has been suggested by multiple posters in this thread, the interpretation of element stresses does not change for triangular plates. Visualize a cross section of unit width and depth = thickness of the element, at the location where the stress is being reported and that would help in...

    Just when you thought Staad couldn't be any worse

    Steve : What is the version of STAAD.Pro you are using ? If not the latest (STAAD.Pro 22.07.00.160), I would suggest using that. This version or as a matter of fact any of the recent versions, should not have this issue.

    Just when you thought Staad couldn't be any worse

    I assume you are referring to the reactions displayed graphically within the reactions box vs those shown in the Support Reactions table ? Can you please upload the .std file and also let us know about the version number of the software you are using? I have to take a look at the model first...

    Results scales with mouse wheel

    Yes I have seen this happening when using the mouse scroll. You may go to the Structure Diagrams > Scale. Check the box named “Apply Immediately” and then you can use the up and down arrow keys to adjust the scale dynamically for any of the items. This should not have the problem. To answer to...

    Demand forces from FE plate results - Concrete design

    Hey Josh, No worries. Good to know that you are with CSI. It's a small world. All the best.

    Demand forces from FE plate results - Concrete design

    Just want to add that the contribution from Mxy is considered in the computation of global moments in STAAD.Pro. If you go to the Bentley Communities forum, you will find a wiki article titled "Global Moments in Plates" which explains this calculation with an example.

    Demand forces from FE plate results - Concrete design

    STAAD.Pro does report Global Moments as you mentioned. You may go to the Postprocessing mode > Plate Results > Go to the Plate Center Stress table and there will be a tab named Global Moments. For meshing where local axes of plates are not oriented the same way and not oriented along the global...

    AISC Advanced Elastic Analysis

    The stability analysis requirements spelled out in Chapter C of the AISC 360-16 specifications is fully implemented in STAAD.Pro. However the provisions of Appendix 1, go far beyond accommodating the pdelta effects (large + small), accommodating imperfections through notional loads and...

    Modelling technique masonry wall in STAAD pro

    Using enforced support is the correct approach. Please make sure that you are putting in the settlements with proper signs at the right support locations. Also since plate stresses are reported with respect to local axes of plates, please make sure that all your plate local axes are oriented the...

    Underground Water Tank Analysis using STAAD - query on support condition

    PLATE MAT DIR Y with compression only attribute would be adequate for the bottom.

    Software Migration

    humanengr : Not sure if your engineers are using the STAAD.Pro CONNECT Edition as that has a new GUI and a new physical modeler specifically for those who prefer physical modeling. STAAD Foundation Advanced (for foundation design) and RAM Connection (for the connection design) are tools that...

    Parking Roof Design

    You mentioned about the roof beams not being connected. For the load to be distributed correctly, you need to ensure that connectivity between the structural members is proper. The fact that the software is selecting small sections for the columns, may have something to do with the fact that...

    Thermal loads in Dynamic model

    Yes you can do that in STAAD.Pro.

    How to model buoy anchor system

    The buoy would be supported by the buoyant force from underneath and the cables. So if you apply the buoyancy as a force on the buoy in addition to any loads from the floating boom, I think it should work. The cables can be specified as tension members and anchors can be defined as pinned...

    Combined Section Wide Flange w/ Channel

    Yes it applies the same rules as you would apply when designing a wide flange. The cross sectional properties used are for the built up section.

    Combined Section Wide Flange w/ Channel

    Section Wizard calculates the cross sectional properties of the built up section based on the geometry. When exporting the section as a General Section from Section Wizard to STAAD.Pro, the calculated properties are shown (for your reference) within the General Section form that is displayed...

    3D plate modelling STAAD Pro

    Couple of additions with respect to the point 3. If you are trying to release the MX moment ( for plates MX is moment ABOUT the local Y axis) then option 1 would be the way to go. However I see that you have applied the release to 2 of 4 plates that are meeting at every node. You may want to...
