    Bentley Structural, microstation and Solidworks

    My firm just started using Bentley Structural (a BIM software) which is used inside of Microstation and we had Solidworks for a single project a couple months back. When I import a 3d structural model from Bentley Structural into Solidworks it does not recognize the structural shapes. Every...

    Extendable/Retractable Platform

    I am working on a project that features a "telescoping" structure where people will sit (however, people will not be on it when it extends or retracts). Furthermore, it features two cantilever platforms that both extend (i.e., as the first platform reaches its most extended point, the second...

    Stone Wall Foundation Fire

    I have a project involving a structural evaluation where a fire occurred in a corner room. The flame traveled up the exterior wall, which is made of field stone. This wall was built in 1803. Is there any documentation on the heating/fire affects on stone, stone walls/foundations and its...

    Post-Frame Building Design

    Mike, Thanks for the info. Can you suggest a good reference/document to read to better understand pole structures? Currently, I have the following documents on hand for review: 1. Post-Frame Building Design Manual by National Frame Builders Association December 2, 1999 2. Pole Building...

    Post-Frame Building Design

    If 1/2 inch plywood is attached to the bottom of the bottom chords, would this reduce the lateral thrust from the scissor truss? and would that provide for an adequate diaphragm? Also, the contractor is proposing to use a standing seam metal deck, similar to what he used on the roof, for...

    Post-Frame Building Design

    What are the criteria to consider when designing a post-frame building (pole barn) that utilizes a scissor truss instead of a standard roof truss configuration? Thanks.

    Thanks for the help, johnny cash. JoshPlum: Does STAAD Pro do this? Thanks

    Deflection Diagrams

    I think I just figured out what you were talking about, johnny cash. After you click solve, you select "Batch Solution of Marked Combinations" under solution choices. However, I have moving loads (structural framing members for an overhead crane) and it brings up an error message: "Load...

    Deflection Diagrams

    I just looked through RISA help, it states: In the Show Deflected Shape For... section of the tab you may specify that a deflected shape be drawn in the current model view based on either a load combination (if a single or batch static solution has been done) or a mode shape (if a dynamic...

    Deflection Diagrams

    Well, I guess I have not been running a batch solution and am not exactly sure where to look either... How do I determine this. Thank you.

    Deflection Diagrams

    I want to display the deflection diagrams of my structure in RISA, but RISA is not even allowing me to check the boxes. How do I get RISA to display the deflection diagrams. (FYI: I have solved the structure in RISA.) Thanks!

    Shear area of Semicircular Lug

    I did a brief google search and can't find the document. If you could post the .pdf that would be great. Thank you.

    Shear area of Semicircular Lug

    I am also getting referrals to the following publications to calculate the exact area of shear plane on a semi-circular ended lug: “Pinned Connection Strength and Behavior,” Journal of Structural Engineering, Vol. 132, No. 2, American Society of Civil Engineers, Reston, VA, 2006. “ASME BTH-1...

    Shear area of Semicircular Lug

    Yes miecz, I have the paper by Tolbert and Hackett "Experimental Investigation of Lug Stresses and Failures," (1974) but it does not give the area equation for the semicircular lug.
