How is the effective depth for beam being calculated for a beam with two or more numbers of layers in RCDC software?
Please provide the basis and validation for the same.
I could find some formula related to effective depth in FAQ in the link below, but that is not giving correct value for the design I have.
Hello, In reinforced Concrete, how will you compute for the effective depth if the column has different rebar, like in this pic. And also for the d'.
The column has 4-25mm corner rebar and 8-20mm side rebar. It is also symmetrical and the size is 500×500mm. With 10mm lateral tie and 40mm as its concrete cover.
The clear cover that is considered in RCDC is the clear cover to the main Longitudinal Bar and not the Link.
So, in the above example, the Deff for column would be calculated as:
Deff = 500 - 40 - 25/2 = 447mm.
Hope this clarifies.
