Structural steel goal post construction 

Hi Rob ! Your teaching is great ! Wich type of foundation you use for this case ? ‘Cause if you use bending connection between column and beam... will appear a moment in foundation. Or is it better use a shear connection between column and beam ?

Thanks, really nice clear explanation!

This is such an excellent video...extremely useful. Thanks Robin

I love how you textured the box in Sketchup to match your real world demonstration, keep up the great work 👍🏻

These videos are brilliant,thanks. I commission structural design on a weekly basis for my projects and like to understand as much as possible, I could never figure the logic of the connection details from column to beam but have always felt silly asking, this has really helped me understand...thanks

Great video. Thanks.

Great explanation!

Glad I’ve found your videos rob very interesting 👍 I’ve recently just put a doorway into an integral garage,it’s a 3 storey middle townhouse,the wall where the new doorway is,is the separation wall from garage to a bedroom and is single skin 140mm blockwork ,it supports the first floor joist but the wall does not continue up as the 1st floor is open plan with a big steel beam going the full length of the house(steel holds second floor joist up)the steel is pretty much inline with the buttress wall on GF.The doorway opening is 920mm and the lintel is a concrete 140x140mmx1200mm and has a bearing each end of around 125mm,the new doorway is close to the rear external wall and is of traditional build 100block 100cavity 100stonework 3 storey high (think it’s classed as a supporting wall) and the new opening is in the buttress wall , the nib that is left is around 530mm closest to the supporting wall. Am I right in thinking this is ok, it has been passed by bc but after reading into approved doc A a nib has to be minimum of 550 with one opening being in the buttress wall . Wher as mine has the opening in the buttress wall 530mm buttress nib then the external supporting wall has a doorway either side of the centre line of the nib and both external nibs left and right are about 300mm.is this ok🤔 sorry if it doesn’t make sense but any info would be great before I consult an SE ,cheers 👍👍

Good info.👍

great good sketchup animation

Good job

Hi Rob, Could you compare goal post with box frame often use in UK ?

Great video. When designing a goal post frame do you use a tie rod below the opening to restrain the base of the columns from 'kicking out' or do you design the foundations to take the horizontal loading. I normally design with a tie at ground floor level but I have recently had queries from Architects saying that other Structural Engineers do not put these in. If you design the foundations to take the horizontal load it can make the pad foundations quite large! Just wondering what you would normally do.

Very interesting, thank you. One question, how should you go about tying the columns to the inner leaf of masonry which sits either side of each column?

I'm a recent subscriber and I'm enjoying the videos. What software did you use for sketching in this video?

What's the difference between a goal-post and a box-frame system Robin? In what instance would you use a box-frame? Thanks

Great Video, what is deemed a good acceptable masonry at either side to warrant non goal post design.

I am a welder this is just a question wouldn’t it be more Ideal to set the lateral beam on top of the columns? I would think you would have more downward support for the dead weight, rather than relying on just bolts

Hi Rob! By putting the steel inside the cavity, what implications would occur in terms of thermal bridging?

Good video. Is it acceptable to use bolts to connect the beams like this? What is the benefit to that rather than placing the beam on top of the columns?

Hi Robin. Great content, thanks for taking the time to make it. On a related matter, if an internal wall is being removed that doesn't provide restraint against wind loading (e.g. wall in mid terrace house) then posts aren't needed and the beam to replace the wall can generally be supported on the masonry walls perpendicular to it? Speaking in a general sense of course. All the best.

Also, for the connection of the column back to the wall wouldn't you put slotted holes to allow for some possible settlement of the goalpost system?

Thoughts on the beam sitting on top of the column instead of connections to the columns flange?

Quality video! What software do you use was that google sketch up? Also, when I look at structural goal posts solutions, a lot of Americans always use a bottom beam tying the bottom of the columns together? - Why is this ? I see no benefit to it at all.

Just had drawing through for mine and getting slightly confused, one end is a 1mx1mx1m concrete pad that’s cool, the other it says an L shaped concrete spreader but not sure where that goes, I get the rest and the wall ties but just the last foundation bit 😂

Think that goal post frame for that teabag box is over designed ;)

The problem isn't the structure - Asda decaf just doesn't have the strength. Try a decent Yorkshire tea, brewed 5 mins, add sugar, and your house will stay up fine.
