Vertical members that are part of a building frame are subjected to combined axial loads and bending moments. These forces develop due to external loads, such as dead, live, and wind loads. Simply put, an interaction diagram (or curve) displays the combinations of the acceptable moment and axial capacities of a structural member.

This design example, "Interaction Diagrams for Concrete Columns," works through the procedure to draw an interaction diagram for a 12 x 12 in. non-slender tied (non-spiral) column reinforced with four # 8 bars bending around its x-axis. The example follows the provisions of ACI 318-05, Building Code Requirements for Structural Concrete. PDF Combined Axial and Bending in Columns - University of Alabama Every point on the interaction diagram has a unique ratio of e P M n n = φ φ. Therefore, if e p M P M u u n n = = φ φ and φ Mn > Mu and φ Pn > Pu, then the column is adequate. Example Check a 16" x 16" column with 5 #9 bars in each face to see if it is adequate for Pu = 390k, M u = 220 k-ft. f'c = 3000 psi, fy = 60,000 psi. 1. Compute eccentricity of loads: 2. Circular Column Interaction Diagram Spreadsheet - CivilWeb The column interaction diagram shows the designer at a glance where the column design can be optimised. The chart shows the designer the limits for each standard bar size at the chosen spacing. If the designer has a particular maximum or minimum bar size in mind it is simple for them to tweak the column size and the reinforcement spacing to suit.

Concrete Column Design - Structural Overview | ASDIP Software The end result is a 3D interaction diagram. To check the adequacy of the design, the actual factored and magnified loads should be compared to the structural strength of the column, as described by the interaction diagram. The images below show the uniaxial and biaxial interaction diagrams generated by ASDIP CONCRETE. P-m Characteristics of Reinforced Concrete Sections Axial load-moment interaction diagrams (P-M) are used as a design aid by engineers to ensure that a reinforced concrete beam-column has sufficient capacity to carry design axial loads and moments, as well as ensuring sufficient ductility in the case of seismic design. This manuscript provides a two-part parametric study investigating the Column Interaction Diagram - The Structural World Interaction Diagram in a column is a graph which shows a plot for the axial load Pn that a column could carry versus its moment capacity, Mn. This diagram is very useful in analyzing the strength of column which varies according to its loads and moments.
