Biaxial bending in columns Interaction diagrams for biaxial bending
Biaxial bending in columns Design Procedure for biaxial bending: A- Determine reinforcement based on the biaxial bending capacity: 1- Determine the dimensions based on a reasonable stress in the column. 2- Determine g in the week axis direction (any direction for square sections. 3- Calculate the biaxial bending moment in the week axis direction. 4- Use an interaction diagram to design the reinforcement for the section. B- Use the Bresler equation to check the axial capacity of the section 1- Calculate Pnx from the interaction diagram assuming only Mnx is applied. 2- Calculate Pny from the interaction diagram assuming only Mny is applied. 3- Calculate P0. 4- Calculate Pnand check
