Sloped vs Stepped Diaphragm
Sloped vs Stepped Diaphragm
(OP)
I am designing a concrete deck with landscaping on top. As the grade of the landscaping varies, my top of slab elevation needs to vary with it. I either have the option of sloping the deck or I can step the deck at the column lines. The landscape architect wants a stepped deck as it works out better for him, But purely from a structural point of view I think it would be better to slope the deck as it would help transfer the lateral forces better. Any input would be appreciated.

Another advantage of the sloped deck with independent tiers, if the function of the building changes (or ownership decides they don't want a landscaped roof because they get ugly when not maintained), a sloped deck affords this change much better than a cast-tiered design.
