Hi Liam,
Thank you for your response! Yes I added stiffeners.
Hi JLNJ,
Thank you for your help! Yes, As you said what I worried about is the torsional rotation of the column if lifting load is out of plane. But how deep is the calculation should go, should I check the torsion stress? That’s a...
Hi all,
I am designing 4-points lifting lugs on columns for a modularized building, because of some restrictions, the lug has to be put on the flange of the column where there is no horizontal beam, and the column is sitting on a longitudinal beam, see the attached. The lug is designed for 25...
Hi all,
What is the design considerations regarding the punching force on a SCH 40 pipe with a thin wall thickness(0.15in) when welding a thicker plate (3/8in)? AISC has lots of design information on round HSS, but not pipe. Can I apply the same connection design concept to pipe? Does the...
Hi Dik, hi Kootk,
Thank you.
I like to use bolts or screws. But the WF flanges is a lot thicker than the C section of CFS. In AISI, welding is the only method mentioned that can be used for any position, i.e. sheet to sheet or sheet to thicker steel members. Can I say that welding is the best...
Hello everyone,
Can anyone tell me what the method of connection between a cold-formed steel member (C section) and a thicker WF steel member is, by using welding, bolts or screws? any thoughts are appreciated.
Hello every one,
I am designing a one floor industrial building (modularized in shop then transported to the site, lift and erect at site)located in a cold place so the building needs to be well insulated. we have two options for lifting the module on site:
1)on the top of the column;
2)or...
I have a building which the client wants to add a 9 ft high partition wall(no door on the wall, and the building height is 12ft) to separate the room, do I need to add wind load on this partition wall? any thoughts are appreciated.
I have a project that the tank was installed offset from the designed centerline on the concrete ringwall by 8 in, and the client does not want to re-install the tank. one proposed solution now is to push grout into the engineering fill under tank foundation throught the ring wall(penetrate...
