HSS beam to Wide flange column web connection

HSS beam to Wide flange column web connection

HSS beam to Wide flange column web connection

I need to design a HSS beam to Wide flange column connection. Beam frames in to the web of the column. It is a shear connection.
Any suggestions for the type of connections that can be used.


RE: HSS beam to Wide flange column web connection

I think the simplest is to have an end plate on the tube that bolts to the web.

If you will have difficulty erecting the tube (between the flanges) then I would weld a flat plate across the column flanges to mate with end plate on the tube.

RE: HSS beam to Wide flange column web connection

Thanks everyone.

We did a detail similar to the 2nd option suggested by jike.

RE: HSS beam to Wide flange column web connection

Just for the sake of discussion mystruct, I think detail by asixth is also cool, and if you remove his stiffeners(top and bottom plates) it becomes a simple shear tab. You can check if stiffeners are necessary or not by simple check(see blodgett)

Shear tabs eliminate drilling into the webs of columns and can be used when beams frame from both sides of the column web. And there will be a lot of maneuvering space during erection work


RE: HSS beam to Wide flange column web connection

Just FYI. A standard shear tab to a column web is difficult to erect. Especially if framing column web to column web.  An extended single plate is easier to erect. Design is required for the eccentricity.

The end plate connect is easier and cheaper to fabricate. But creates a fixed connection.

White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
