Topic: Embedded Reinforcement dimension
In ATENA GiD, you have to put a dimension of embedded reinforcement. What is the dimension of this embedded reinforcement and how this dimension affects the analysis? I have done some trial analysis with different dimensions and the results vary significantly with the dimension.
In modeling the bond of reinforcement, what does it mean by confined and uncofined concrete? In theory manual, it says..unconfined (failure by splitting of the concrete) and confined (failure by shearing of concrete between the ribs). If I am modelling a beam with shear reinforcement and ribbed bar, will it be counted as confined or unconfined?
If the mesh size is 50 mm and estimated crack spacing is 100mm, then will it make any difference by using the "activate crack spacing" function?
