How would you go about the steel columns being adjacent where an expansion joint is expected?
The building is a steel building with a composite slab.
The expansion joint is required because the building is 60m in length.
The problem is where the expansion joint is expected, the columns are ...

Buckling length of continuous steel H columns in multi story buildings
I have seen that steel columns in multiple story buildings span multiple stories, in that case how do you calculate the buckling length for the column? do you take the whole column's height, or just ...

Conflicting steel strength Vs temperature graphs, NIST NCSTAR vs Engineering Toolbox
This graph is from NIST NCSTAR 1-6C
And this graph is from the Engineering Toolbox.
As you can see, neither the NIST yield or tensile curves match with the ET structural steel curve. Why? And which ...

Pull out force for a 5/8" tapped bolt
I am looking for the pull out force on a 5/8" bolt tapped into 1/4" thick tube steel.
Does the thickness of the steel need to match or be greater then the bolt diameter?

How to assess the stiffness of a hollow steel section joint?
Hollow steel sections are used often in trusses:
I've been taught that the advantage of a truss structure is that it can be stiff without any of the members being under bending moment. This is an ...

Why is the yield strength of steel assumed to be less for a thicker element?
The above image is part of table 3.1 of Eurocode steel design standard. Looking for example at the first row (steel grade S 235), we see that there are two values for yield strength $f_y$, one for ...

Is it structurally sound to cut an I beam to a T on one end?
I'd like to confirm whether the replaced beam in the attached picture is structurally sound given the end was cut to a T instead of an I. I had a qualified structural engineer approve the work but I'm ...
