The conversation between human and AI assistant.
How can we determine a beam weather its singly reinforced or doubly reinforced just by looking at it?
What other differences are there between singly and doubly reinforced beams?
While the presence of rebars is the most visible difference, there are also differences in how the reinforcement is calculated and placed within the beam. Singly reinforced beams have reinforcement only on one face and the reinforcement is placed in the tension zone, whereas doubly reinforced beams have reinforcement on both faces and often have a larger compressive reinforcement compared to singly reinforced beams.
