Title
Abstract:
In the following essay will talk about the benefits that the materials used as concrete and steel together in the construction of buildings or structures for earthquake resistance. Which it will be explained that the mechanical properties are improved due to the use of these materials are. Finally, the importance of knowing how you can combine the mechanical properties of two or more materials be established.
Key words: Materials, Concrete, Steel, Mechanical Properties
Introduction:
Many materials are used daily not only in the construction of buildings but also in the manufacture of machines, which are subject to high stresses. The combination of materials can influence the performance of certain machine or structure.
In engineering issues you need to identify materials that are more efficient for a particular function, in this case, a structure is earthquake resistant as possible, especially in highly crowded urban areas.
Development
Concrete is a material having a high resistance to compressive stresses, but is generally associated with several armor made of steel, which is what we know as reinforced concrete. But why the need to associate it with steel? Although it has a good compression behavior, not facing other efforts, such as shear, tensile, bending, etc. Is steel which is responsible to compensate for these weaknesses of the concrete.
These weaknesses of which we speak, are offset by increasing certain mechanical properties.
Armatures for concrete can be of corrugated steel, which gives not only strength but also flexibility for this to be more deformable, therefore, this provides him with high ductility. This allows it to absorb energy in the event of an earthquake. Besides this, thanks to the steel, increases its adhesiveness and thus becomes a compact structure.
This in case of structures, but applies to many other fields.
If we realize the above is just a case of the millions that occur daily and that are part of our daily lives where other elements are mixed or come together so that the result has mechanical properties of both materials and therefore be more effective and more efficient.
We must be aware that safety factors engineering products should be increased, i.e., there is less risk to human life. Because of this essential that methods by which the performance of the product is increased are analyzed. These factors can be increased from the selection of materials to be used for production
Conclusions:
Finally, we can say that we must be aware and give much importance to the selection of materials at the time of a project. You really think about the implications of the not make a correct selection of materials? How many lives can be affected because of that, or how many could be missing, depending on the size of the project? Not only that, but we must also think beyond things, analyze, propose ideas, and try to optimize the materials we use in terms of the role.
