Hello. I was curious about the support reactions of a continuous beam with 4 spans. The end reactions are pins but the middle three reactions are springs (i.e. they aren't pinned, they are simply bearing over a surface). Does the fact that these supports are springs affect the reactions? Please...

My thoughts exactly. Something is not right here. Perhaps they will not be removing the Primary I beam. But again, I don't understand why the engineer of record would specify on the demolition plans that the OWSJ should be shored and not the primary I beam. Very odd to me.
Hi all.
I'm currently designing a shoring system for a demolition job on an existing structure. It's a 2-storey steel structure with open web steel joists as secondary beams and I beams as primary beams. They are removing columns along the middle portion of the building and the primary beam...
Thank you for the response @Enable. The bearing length of the angle iron is 6" and our beam width is about 3" so it will easily be laying completely on the angle iron. The angle iron would still be flush against the wall. I modified my sketch to show where I was thinking of putting the piece of...
Hi all,
I attached a sketch (side view) of a problem I'm looking to solve. Blue represents the beam, red is the angle iron, and black is the concrete slab and wall. It consists of a set of beams that extend past the slab and are flush with the opposite concrete wall. To avoid the beams being in...
Hi ggcdn,
Thanks very much for your response. That certainly makes sense. So the tie is supposed to go through the slab and run parallel to the surface of the slab if i understand correctly? But I find it odd that it does not mention what length of tie should go through the slab. Should the tie...
Hello, I'd like some help on the aforementioned CSA clause in the title of this post. I am confused with the last sentence of the clause. The clause relates to ties in concrete compression members (columns) and the maximum distance of the final top tie from the slab/drop panel at the top of a...
