What is the primary function of it in construction?

The primary function of reinforced concrete in construction is to resist structural loads. This role is crucial because buildings and structures must withstand various forces, including the weight of the structure itself (dead loads), the weight of occupants and furniture (live loads), environmental loads such as wind and snow, and seismic forces. Reinforced concrete incorporates steel bars or mesh, which enhance its ability to withstand tension, allowing the material to maintain structural integrity under these loads.

The composite action of steel and concrete allows reinforced concrete to carry loads more effectively than concrete alone, which has limited tensile strength. Therefore, reinforced concrete systems are designed explicitly for load-bearing applications, ensuring safety and performance of the built environment. The connection of structural elements or the provision of shear strength, while significant, are secondary to this fundamental aspect of load resistance.
