Why long-term analysis? Edge beams are beneficial for punching shear and unbalanced moment.milkshakelake said:With my suggestion, some of the slab is left "unsupported." It's not technically unsupported, just slightly more discontinuous than I like. You can do long-term deflection analysis for this,
Do you mean the green one in the attached image below:milkshakelake said:or add more beams around the lift.
Do you mean the ones in the attached image below:milkshakelake said:Or add another column at the corner of the lifts (which will also remove some of the beams)
I can't catch this. Can you elaborate more?milkshakelake said:4. Don't really need beams around the stair openings. Think of it like the corner of a building with a cantilever slab for the stair landing.
Yes, there's no slab there.milkshakelake said:I think there's no slab there. It would become an exposed beam.
If you have concrete wall around lift then you don't need those beams (over wall) as you have a continuous support but you need that red column to avoid having a cantilevered slabhoshang (Civil/Environmental)(OP) said:Please mind that there are concrete walls around the cross locations in original post image (lifts).
You literally have only half of the column supporting the slab which is critical. Preferably, shift inside (to the left) so both edges of slab and columns are aligned.hoshang (Civil/Environmental)(OP) said:Punching shear possible issue, move col
The adjacent bay to the stair is 7m wide (it's for toilets), and the stair is 4.3m wide. Where the column should be moved?
milkshakelake said:No need for beams here
milkshakelake said:It's same thing as edge of building.
If I understand correctly, no beams required at the edge of the building. Aren't edge beams helpful for punching shear resistance?BulbTheBuilder_EI said:Same thing as the edge of the building. No beams required. You don't need beams (structurally)
