A structure refers to a system of connected parts that is used to support a
load (Hibbeler, 2012). When designing a structure to perform a specific function, the
engineers must consider their safety, aesthetics, and ease of maintenance as well
consider the economic and environmental limitations. Generally, this requires
various independent studies of different possible solutions before determining
finally, what structure is the most suitable. This design process is both creative and
technical, and requires a basic understanding of the properties and laws of materials. The
Mechanical principles are paramount as they determine the material's response once
preliminary design of the structure proposed.
To analyze the structure correctly, it is necessary to make some idealizations of how
the elements are connected and support each other. The load is determined according to the
norms and building codes of the country, on the other hand, strength and displacement in the
element is being applied using the theory of structural analysis. The results of the analysis
they can be used to redesign the structure. Therefore, the structural design comes from a
series of successive approximations, in which each cycle requires a structural analysis
(Hibbeler, 2012).
Classification of structural elements
Tension members: They are structural elements that bear tensile forces, called tension members.
According to the nature of the load they bear, they are usually very thin. There are several options.
in the market, but the most famous are rods, rods, angles, etc.
Beams: Horizontal, straight elements; designed to support vertical loads.
the design is based on supporting bending moments. If it were the case of a short beam this
it would withstand large loads, there are iron and concrete alloys that together form a
a solid piece that withstands tensile and compressive stresses, usually found
rectangular sections as it facilitates their on-site construction.
Columns: Vertical, straight elements; designed to support axial compression loads.
they can be square or circular; in the vast majority of cases, cast with concrete and
reinforcement bars.
Types of Structures
Armors: They are thin elements, generally arranged in triangles. Due to the
geometric arrangement of its components, it deforms and turns into a load of
tensile and compressive forces in the element.
Cables: Used to cover long distances, they are flexible, withstand tension loads, and are used
as support in bridges
Arches: Just as cables cover long distances, it withstands compressive resistance,
but it must be rigid in order to maintain its shape, used in bridges and coverings for walls
of masonry.
Composed of beams and columns connected rigidly or through joints,
the resistance of a frame derives from the moment interactions between beams and columns of the
rigid unions.
Composite structures
Mixed elements are defined as composite elements of concrete and steel.
structural or cold-formed, physically interconnected through connectors to
limit the longitudinal movement between the concrete and the steel; and preventing separation of
a member with another.
Generally, this combination does not significantly affect the structural analysis, since it
can be broken down into uniform parts, and common terminology can be accepted
steel and reinforced concrete structures and the design and calculation standards
corresponding. But in other cases, the integration is tighter, affecting the
basic elements that constitute it, and the material cannot be analyzed in isolation; this
it will be called mixed concrete and steel structure in this project, which can be
checking by optimizing the performance of the components. Its rationality.
The general, this combination does not substantially affect the analysis of the structure, since
for this, it is broken down into homogeneous parts and the usual terminology of structures of
steel and reinforced concrete, with their corresponding design and calculation criteria, results in
acceptable. But on other occasions, the integration is closer affecting the elements
basics that constitute it and the isolated analysis of materials is not possible; it goes to this point
referring in this project, the mixed structures of concrete and steel, which can be justified
for the optimization in the behavior of components.
