Sloped Reinforced Concrete Slab
Sloped Reinforced Concrete Slab
(OP)
Hi all:
We are designing a two story home where the sloped roof (10:12) is going to be reinforced concrete slab (one way for analysis).
I would like to hear if someone has dealt with this situation before, I am thinking in considering the ridge as a rigid support as it is going to be nearly perpendicular to the slab on the other side (gable roof).
Also there is going to be outward thrust at the CMU wall support on the other side. I am thinking that the beam would be subject to the lateral force as well as the gravity component.
Your thoughts are welcome.

With a high pitch, yes the component in line with the intersecting roof plane can be taken by the opposing roof diaphragm, but the other orthogonal component must be dealt with as well.

If you provide a ridge beam which can span from gable to gable wall or other support , then slabs could be designed as spanning from side walls to ridge beam. In this case there will be no thrust on the side walls.
