opening in 1-way slab
opening in 1-way slab
(OP)
I have a slab with a 2:1 dimension ratio overall. This is complicated by an approximately square opening adjacent to one of the beams, between which the rc slab spans. The slab span is about 30', while the opening is approximately 10' wide. My intuition is that this shouldn't force me to reconsider the slab as 2-way. On the other hand, I probably have to frame out the opening with headers for reinforcement. What's the standard way of dealing with skylights and elevator shafts in 1way slab?

For small opening, it could be handled by providing additional reinf, or push the bars fall within the opening, to its sides. However, for large opening, this method would likelt to cause congestions, and lead to other problems.

Thanks for your thoughts.
What if I used ribbed slab instead of beam-and-slab system? Would you still recommend framing the opening with beams? I'd prefer to avoid these if possible, so as to simplify formwork.
