Interaction Diagrams and Strain Compatibility for Columns The column cross-section is 300 mm x 500 mm and is not in contact with the ground or exposed to the weather. Ties are #10 bars and longitudinal reinforcement is # 19. Concrete compressive strength is 42 MPa and steel yield strength is 420 MPa. Calculate the axial load carrying capacity, OP and flexural capacity OM, for point in the interaction diagram with bending about the 3-3 axis where the tensile strain at the end of the toension of the concrete section is 0.

Answer 1

Tensile strain at the end of the tension of the concrete section is zero
