Hi,
I have a question about effective thickness.
If I consider slab stiffness properties, the effective thickness is the same as the concrete thickness above flutes?
what should I input the effective thickness section?
Please let me know.
Thanks,
Using an effective thickness of the topping concrete and corresponding E value of concrete is one way to consider diaphragm stiffness. It would slightly underestimate the stiffness since it ignores the metal deck and concrete in the flutes of course.
