After the I-90 tunnel in Boston and the NTSB report I am a little concerned using adhesive anchors when subjected to direct tension. Any tips or concerns will be appreciated.
Thank you
I need to design several surface mounted base plates to resist relatively large pull-out and shear forces. Due to spacing and edge distance limitations we are running out of options with regular expansion and epoxy anchors plus the contractor would like to use some type of embeded anchor. Any...
A 14 diamter pipe stub is welded all around on a 24" 90 degrees short radius elbow supporting the riser above. Is there a formula or procedure to determine the stresses on the 90 elbow without running FEA, etc.
I am supporting a cylindrical vessel with a saddle. The perimeter of the bend plate of the saddle is welded to the vessel with intermitent welds.
To properly size the saddle (angle and width, etc) I need to chek the local stresse at the interface with the vessel but I am not sure how to model...
Problem description: I am trying to check the local stresses at the supports of a round pressure vesell (120" diameter 5/8" thick)full of diesel using FEA with STAAD.
Question: Any tips on how to apply the weight of the fluid on the elements?
Note: If we apply the hydrostatic pressure which...
I have a 120" pipe that I would like to check the stresses at the support points. However, I do not know how to simulate the weight of water in the pipe.
I am using STAAD
Any tips would be greatly appreciated.
Thank you,
