R Coefficient - Y

The appropriate type of carrier system is selected from the list according to the ductility level you choose and the type of bearing system in the Y direction. According to the previous selections, some building types are not allowed to be selected at this step within the scope of the principles specified in TDBY 2018.

How the building behavior coefficient is determined is shown in the flow diagram below.
