• RAM connection Standalone 2023: HSS wall slenderness check in single plate connections.

    Hi, I am writing to report an issue with the RAM Connection Standalone 2023 software. I noticed that when I was designing a W beam to HSS column single plate (shear tab connection), the software did not check the slenderness of the HSS wall as per AISC…

  • OpenSTAAD | OSPropertyUI::CreateHSSRoundPropertyFromTable not available.

    I'm using STAAD.Pro Script Editor and OpenSTAAD API Reference to generate a structural model. Unfortunately, t he OpenSTAAD function (OSPropertyUI::CreateHSSRoundPropertyFromTable) to create HSS Round shapes from table is not available. Question:…

  • Staad and AISC Sesimic Provisions and Tube Shapes

    I have an equipment screen wall frame. The screen wall frame is HSS columns and HSS beams. Bracing is not allowed so we have consider it a moment frame. It is in seismic design category D. Will Staad perform AISC seismic provisions code checks…

  • RAM Connection: HSS Truss Ductility Warning

    RAM Connection CE 13.0 issues a Material Ductility warning in the limits of applicability section when using ASTM A500 Grade C because the vaule is 0.81 and the maximum value is 0.80. The notes in Table K4.2A state that "ASTM A500 Grade C is acceptable…

  • RAM: HSS Column splice defect

    In a HSS column splice connections, checks for the "yielding of the end plate" is taken the same to the "tensile strength of bolts". please advise. Model and results attached. Results.pdf HSS CS error.zip

  • HSS truss connection

    In truss connection of HSS (chord and branch), in the interaction equation (last check) it uses the maximum ratios from each case of loading, when in interaction equation we should use each maximum ratio with its corresponding ratio. Attached a model…

  • RE: Issue on torsion checks of round HSS using AISC 360-10

    For HSS sections, torsion check is automatically carried out. The design parameter TORSION only affects the torsion check for non-HSS sections. Regarding the second part of your question, the HSS torsional constant ( C ) is considered as per the values…

  • OMF Connection to HSS Column

    The project I'm working on is in SDC D (so no R = 3), but we fall into the exception of 12.2.5.6.1 which allows us to use OMF for our situation. Due to architectural constraints, we're looking at using HSS columns with wide flange beams to make up the…

  • ASTM A1085 HSS in STAAD?

    With the new ASTM A1085 spec for HSS you no longer have to use 0.93 times the nominal wall thickness, you can use the nominal wall thickness. When will this be implemented in STAAD? I see it has been in RAM since 2013. I suppose you could use TS sections…

  • RE: Does Ram Connection address a w-shape beam moment connection to an HSS column? The column continues above this cantilever beam condition.

    Yes. In RAM Connection, you can assign the following moment connections for a W-shape beam connected to a HSS column: 1. Diaphragm Plate (Smart Connection - Smart FP Bolted or Smart FP Welded) 2. Directly Welded (Smart Connection - Smart DW) …

  • RE: Ram Connection HSS MEP for Column Splices

    Regretfully our MEP beam splice is limited to wide flange shapes in Ram Connection v11. We still have some work left to implement more HSS connections. I suppose you could look at it as a base plate, but that's not ideal. Limcon currently has a joint…
