What is reinforced concrete and why is it used?
Reinforced concrete is a composite material that consists of concrete embedded with steel bars or wires (called reinforcement) that provide additional strength and ductility to the concrete. Concrete alone is strong in compression but weak in tension, while steel is strong in both compression and tension but susceptible to corrosion. By combining these two materials, reinforced concrete can resist various types of loads and stresses, such as bending, shear, torsion, and temperature changes.
Reinforced concrete is widely used in the construction of buildings, bridges, dams, tunnels, and other structures because of its many advantages over other materials, such as:
It is economical and readily available.
It is durable and fire-resistant.
It can be molded into any shape and size.
It can be prestressed or post-tensioned to increase its strength and reduce cracking.
It can be combined with other materials, such as brick, stone, or steel, to create aesthetically pleasing and functional structures.

FAQs
Here are some frequently asked questions and answers related to the topic of design of reinforced concrete structures ML Gambhir PDF 37.
Q: What is the difference between working stress method and limit state method of design?
A: Working stress method (WSM) is a traditional method of design that is based on the assumption that the stresses in the materials do not exceed their permissible values under service loads. Limit state method (LSM) is a modern method of design that is based on the assumption that the structures should be able to withstand all possible loads without exceeding their ultimate strength or serviceability requirements.
Q: What are the advantages of limit state method over working stress method?
A: Limit state method has several advantages over working stress method, such as:
It is more rational and realistic as it considers both strength and serviceability aspects of design.
It is more economical and efficient as it allows for higher utilization of materials and lower safety factors.
It is more compatible and consistent with the codes and standards used for reinforced concrete design.
Q: What are the types of reinforcement used in reinforced concrete structures?
A: The types of reinforcement used in reinforced concrete structures are:
