How a reinforced concrete structure is calculated

The calculations for a reinforced concrete structure are generally more complex than for a simple concrete structure. Many factors must be taken into account, such as the strength of the concrete, the tensile stress of the steel, the loads on the structure, the geometry of the structure and the design of the reinforcement.

To calculate the strength of a reinforced concrete section, the strength of the concrete and the tensile stress of the steel must be taken into account. The strength of concrete is measured in MPa (megapascals) and can be obtained from the equation:

R = 0.85 f c √ √ A c

where:

• R = resistance of the reinforced concrete section (MPa)
• f c = compressive strength of concrete (MPa)
• A c = area of ​​the concrete section (m 2 )

The tensile stress of steel is measured in MPa and can be obtained from the equation:

T = f y √ √ A s

where:

• T = tensile stress of steel (MPa)
• f y = yield strength of steel (MPa)
• A s = area of ​​the steel section (m 2 )

To calculate the load on a reinforced concrete structure, the loads on the structure and the geometry of the structure must be taken into account. The loads on the structure can be classified into permanent loads and variable loads. Permanent loads must be taken into account in the design of the structure, while variable loads must only be taken into account if they are expected to occur during the use of the structure.

The geometry of the structure can be classified into straight sections and can be

How a reinforced concrete column is calculated

The reinforced concrete column is calculated by using the formula P = EI , where P is the maximum load that the column can resist, E is the modulus of elasticity of the concrete, and I is the moment of inertia of the cross section of the column. column. The load P is given in newtons (N) and the moment of inertia I is given in square meters (m 2 ).

To calculate the load P , it is necessary to know the axial load and the wind load. Axial load is the sum of all forces acting in one direction, while wind load is the sum of all forces acting in a direction perpendicular to the axial load.

Once the loads are known, the moment of inertia I of the cross section of the column can be calculated. The moment of inertia can be calculated using the formula I = bh 3 /12 , where b is the width of the cross section of the column and h is its height.

Finally, the load P is calculated using the formula P = EI .

What types of structures are built with reinforced concrete

Reinforced concrete is a material composed of cement, aggregates and metal fibers, which is used in the construction of concrete structures. It is a very versatile material, which can be used to build a wide variety of structures, such as buildings, bridges, dams, roads, etc.

Reinforced concrete is characterized by its great resistance to traction and compression, which makes it ideal for the construction of structures that support heavy weights. In addition, it is a material that is highly resistant to the elements and to chemical agents, which makes it ideal for the construction of structures in places exposed to adverse conditions.

How reinforced concrete is prepared in a construction site

Reinforced concrete is a mixture of cement, sand and gravel with steel fibers that is used to construct the structures of buildings. It is a very resistant material that, once dry, can support great weights and loads.

To prepare the reinforced concrete in a construction site, a mixer of cement, sand, gravel and water is needed. First, the dry ingredients are put into the mixer, and then the water is added. Let everything mix for a few minutes and, once it is ready, it can be used.

It is important to note that reinforced concrete has to be completely dry before it can be used. If used before it is completely dry, it may not hold the weight or load that will be required of it.

This course deals with the calculation of reinforced concrete structures. Basic concepts are explained and calculation examples are provided.
