Since this is an existing installation, lifting the unit to install isolation directly beneath it would be costly and complicated. I’m exploring whether it would be more practical to shore the structure temporarily and install isolation pads between structural framing elements instead like at...
Yes — the unit is currently causing noticeable vibration.

I'm currently researching vibration isolation methods for a residential project where a rooftop mechanical unit is supported by wood framing. I’m curious if anyone has dealt with a similar setup and can share their experience.
Would it be more effective to isolate just the equipment base, or...

I am designing a single shear tab (extended shear plate) connection for a W6×15 beam supporting mechanical equipment. However, I am facing challenges due to edge distance limitations and the fact that the AISC manual permits the column to be designed for axial force without eccentricity. Since...
I am working on designing a bolted beam splice connection for a W-Beam, with the splice located at one-third of the beam's length. However, after reviewing the AISC Steel Construction Manual (15th Edition, Volume 1), I was unable to find an example that specifically addresses this type of...
Hi EngDM,
That's great advice! I'll definitely consider that.
Hi JoshPlumSE,
All the information you shared is perfect for me to start. I will give it a try and let you all know my solution!
Thanks!
Hi JoshPlumSE and EngDM,
Thank you for your help! I am working on designing for increased capacity. Do you have any example problems that I can refer to?
Hi everyone,
I have a question about designing a composite column with HSS infilled with concrete. I'm not quite sure how to approach this in RISA-3D. Does anyone have any suggestions or guidance on how to get started?
Thanks in...
I am looking for the dead load of this grating to design the structure below. I haven't been able to find any resources for this specific size of grating. Grating (field note):
1. Width: 5' - 7 1/2"
2. Span: 26' - 3/8"
3. Bearing Bar Depth: 5 1/2"
4. Bearing Bar Thickness: 1/4"
5. Bearing Bar...
Should I treat it as flat roof or gable/hip < 7 degree? https://files.engineering.com/getfile.aspx?folder=8eb38e2c-bd85-4dd6-b02f-ab7509b9f38a&file=Screenshot_2024-06-19_115819.png
