Interaction diagram circular reinforced concrete column aci 318 14 develop an interaction diagram for the circular concrete column shown in the figure below about the x axis. Red line represents column failure. Kramer calculate p n m n by applying forces to free body diagram 79 95 kips 89 43 kips 489 60 kips moment arms will be in inches must convert to feet for desired units.
This videos gives an introduction to reinforced column design by using interaction diagrams.
Interaction diagram tied reinforced concrete column. Interaction diagrams for concrete columns d d. A column interaction diagram is a visual representation of the combined loads bending and axial that will cause the column to fail. 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.
