a) How does increasing the yield stress of the tension reinforcement affect the nominal strength and ductility of a reinforced concrete beam? Why?
a) How does increasing the specified concrete strength affect the nominal strength and ductility of a reinforced concrete beam? Why?
What does over-reinforced mean? What does under-reinforced mean? Which is desirable and why?
How would your Moment-Curvature plot be affected if the amount of tension steel was doubled?
How would your Moment-Curvature plot from part a be affected if compression steel was added to the cross-section?
What is the significance of the yield moment?
