    Old Simpson Wood Connectors

    Lexpatrie, the OP notes, "the existing drawings were permitted in 1965..." Sounds like the best option is to reach out to Simpson and ask for their help/recommendations.

    Old Simpson Wood Connectors

    I am trying to determine the capacity of old Simpson wood connectors from a set of existing drawings - does anyone have any ideas or pointers for where I can find this information? The existing drawings were permitted in 1965 and note, "JOIST HANGERS SHALL BE SIMPSON TYPE F, Fd, OR 8 OR EQUAL...

    Walking Pace/Speed for Floor Vibrations

    271828, The walking speed is the crux of my question. We are using walking speeds based on the DG 11 recommendations. We do have corridors within the same bays as the rooms that will have equipment, but those corridors are curved and have many doors (likely more stop-and-go traffic than one long...

    Walking Pace/Speed for Floor Vibrations

    FE_struct1, The criteria is 6000mips is for booms and other equipment that will be in the occupied spaces. We are providing springs and neoprene pads where we are able to, but most of the equipment cannot utilize neoprene pads, springs, or other means of damping. We are using a 5% damping ratio...

    Walking Pace/Speed for Floor Vibrations

    Did some digging - RAM's user manual states that it uses the Second Edition of DG 11 (Section 10.1 of the Steel Beam Manual), but if you dig into the outputs it is actually following the First Edition's provisions and equations. Bentley has stated they are planning to release an update that...

    Walking Pace/Speed for Floor Vibrations

    I am looking for input on walking pace/speed for floor vibration analysis. The structure I am working with is a composite steel framed floor with typical 33'-4" square bays, so fairly long spans. We are using RAM Structural System for our floor vibration analysis. The criteria we are trying to...

    Wood Lateral Analysis Software (Structural)

    I appreciate all the replies and information. I believe I will be pushing for Excel spreadsheets on my projects moving forward. JoshPlumSE: I follow what you are saying about the tension and compression forces not correlating exactly with the shear values but my main concern is the unit and...

    Wood Lateral Analysis Software (Structural)

    I am a structural engineer working on a 5-on-2 wood over concrete podium job. For the wood design, we built a RISAFloor model and then exported to RISA-3D for the lateral analysis. The results we are getting from RISA-3D are essentially junk though (see below) and when I reached out to RISA...
