For the cross section of Figure 4.1(a) and the given tensile reinforcing areas, sketch the moment-curvature relationship. You must include cracking, yielding, and concrete strain values of 0.003, 0.004, 0.005, and 0.006 on your plot.

a. As = (4) - #11 bars (equally spaced in a single row)b. As = (6) - #7 bars (equally spaced in a single row)

Answer 1

Moment Curvature relationship:

The points highlighted are cracking, yielding, and concrete strain values of 0.003, 0.004, 0.005, and 0.006 respectively.
