Theory and Design of Structures I
Reinforced Concrete Design
• Rectangular singly and doubly reinforced beams
• Elastic design
• Limit state design concepts; material strength
• Flexural strength and shear strength of beams;

• Steel reinforcement is introduced into a concrete
beam mainly to carry tension, thereby resulting in a
reinforced concrete (RC) beam.
• Components: concrete and reinforcing bars (rebars)
