How does RAM frame handle joint stiffness reduction when analyzing a steel moment frame? I have a structure with steel moment frames and would like to explore the option of using flexible moment connections. What is the process of reducing joint stiffness in the RAM Frame model and how much does it needs to be reduced?
Thank you.
You can control the dimension of the rigid end zone where the beam and column meet through criteria - general.
You can further affect the beam end stiffness by using Assign - Beams - Frame beam Connection Types.
