Steel connections

[ali-15-04-1993]

Hey guys i want to make a connection like in the attached file as a column beam connection. However i can't find the right type in the steel design connections. Also i want it to be subjected to a shear of 270 kN and nothing else. How is it possible?

Hi,

Option number 1, create your own spreadsheet with all the checks for connection(bolt brake, flange checks, reduced area of cross section....and so on. Then, link this spreadsheet with robot via octopus and you have solved your issue.

Option number two, make your own model by shell element. In this way you can check everything.

Pay attention to your pic, the joint have only one plate that connect the beams with the column. Usually I use two plates with notch in the lower flange of the beam.

Option3: Replace the tube with an I section on a short part of the column where the beam is located. This should allow you to design the shear plate, its welds as well as the bolts.

Sorry i didn't specify my question. I need to design a fin plate on a column made of HEB 300 and Beam of HEM 300 subjected to 270 kN shear. ( see atached file)

OMG,

Follow the suggestions of the previous Artur's post, this is a standard connection, please do some training.

+1 for Artur, this is the way i also use in such cases, but be carefull because actually the shear force acting at the beam's end causes a moment at the centerline of the column (if the connection is modeled as pinned) because of the deistance of the c.m of the column's section and the point that the shear is transfered... This of course also happens in case of not using circular or tubular columns.

Artur can robot generate connection between I beam and box section ?

@Artur.Kosakowski can robot do connection between i beam and box section

HI @belrefai 

This type of connection is not supported.

Refer to Steel connection types in Robot
