most welcome: By stages I mean, how you would construct a bridge. Here are some details if you want to construct a bridge using prestressed precast beams, cast in place slabs, asphalt and barriers. How would you construct it? Disclaimer: the stages have a different numbering system from what I want to mention here. Also, in some regions, the order may be slightly different. Stage 1: build the columns (not included here, because those are considered supports) Stage 1 (really now): Put the beams in their places. Question for this stage: who carries the beam self weight? Answer: the beam itself Stage 2: You cast the slab above the beams but not between them (diaphragm) Q: who carries? A: the beams. The slab is not yet hardened Stage 3: you cast the slab in between the beams and the diaphragm Q: who carries? A: beams with slabs Stage 4: you errect the barriers. Q: who carries everything now? A: girder + slab (composite action) because the slab would have hardened when you add the barrier Stage 5: you pave the asphalt Q: who carries? A: composite action So stages are important because at different stages, different things are responsible for carrying different loads I hope it helped PS: Sorry for the late reply. I had a ton of things to finish and now I am gradually getting back

Hello there. Thanks for this video. What do you mean by stages?

Disclaimer: the stages have a different numbering system from what I want to mention here. Also, in some regions, the order may be slightly different.
Stage 1: build the columns (not included here, because those are considered supports)
Stage 1 (really now): Put the beams in their places.
Question for this stage: who carries the beam self weight?
Answer: the beam itself
Stage 2: You cast the slab above the beams but not between them (diaphragm)
Q: who carries?
A: the beams. The slab is not yet hardened
Stage 3: you cast the slab in between the beams and the diaphragm
Q: who carries?
A: beams with slabs
Stage 4: you errect the barriers.
Q: who carries everything now?
A: girder + slab (composite action) because the slab would have hardened when you add the barrier
Stage 5: you pave the asphalt
Q: who carries?
A: composite action
So stages are important because at different stages, different things are responsible for carrying different loads
I hope it helped
