structural design
Although the field of structural design is broad, the concept of structural design in civil engineering can be summarized as the practice of all activities related to the mathematical modeling and analysis of structures, such as marine infrastructure, and the new millennium sees the emergence of information technology as a driving force behind advances in civil engineering, not Especially in the field of design-related calculations, the increasing improvement of computer software, its availability, the increasing speed of calculations and the ever-decreasing costs, have already had a significant impact on civil engineering, which can be considered a paradigm shift.

Activities in the structural design profession
In fact, in practice, structural engineers must provide quantities of materials to conduct construction surveys, prepare rough budgets, and monitor the construction of structures, so they sometimes need skills other than understanding the modeling of structures from a mathematical and mechanical perspective.
structural design
As mentioned earlier, the activities of building planners are extensive, and they mainly use tools and software to build a simplified structure. However, there are methods for manually calculating some strengths in infrastructure connections, and many of these programs use finite element methods to analyze a structure’s response to various forces, and two of the The two most widely used programs for analyzing structures are ETABS and SAAP2000

Civil engineers also use software such as CYPE CAD or MIDAS for dynamic analysis, i.e. investigating forces whose velocity and value change rapidly, and therefore must be investigated within a certain period of time
Structural design sensitivity analysis concerns the relationship between design variables available to the structural engineer and structural interactions determined by the laws of mechanics, acceptance of interaction measures such as displacement, tension, pressure, natural frequency, torsional load, acoustic behavior, frequency response, vibration noise (NVH), thermoelastic behavior, dimensions, component shape and composition.
Design variables are implicitly determined by critical equations of structural mechanics, where first- and second-order design sensitivity analyzes are presented for static and dynamic responses to both linear and non-linear structural systems, including friction and plastic contact problems.
The designer is usually asked to assess the feasibility of an architectural model, meaning the materials required and whether the structure is economically viable, as well as scenarios that may present challenges during construction from the point of view of
Design, and depending on the type of project, planning, drafting, tendering, construction, etc., civil engineers hold meetings to ensure that all conditions necessary for the construction of the structure are met.

Structural Design Statistics
To simplify the matter a bit, Structural Design Statistics takes into account the composition of the structure and the forces to which it is subjected in order to understand the effects and predict its behavior, all with the aim of determining maximum load and life to failure.
At the most basic level, structural analysis takes into account predetermined forces, gravity, active and dead convection, wind and earthquakes, these loads particularly affect the element, beam, column or slab, the position and direction of the load also affects the effect on the structure, and bending elements affect For some materials also on the service life
structural design
From a mechanical point of view, there are five types of forces: pressure, shear, bending, torsion, and tension. These loads are examined through four types of analysis, dynamic, static, stability and vibration. The choice between the two will depend on environmental conditions and the use of the structure. Building professionals are to determine if a material upgrade is required to ensure balance, safety and durability of the building and, in extreme cases or in the early construction phase, hold discussions with architects to change dimensions or reposition the elements

Fields of work for structural engineers
Here are some of the areas in which a structural engineer can work from planning to construction, where planners can choose from a variety of activities which are
sustainable design and construction
Planners working in sustainable building use the latest technologies to improve and improve the environment, and in addition to the social impact of city designs, sustainable building demands that the protection of animals and plants as well as human well-being be placed above construction costs.
Construction assessment and inspection
In the final stages of construction, designers are sometimes asked to review reports from field engineers and go to the construction site. In these reports you will find materials, dimensions, and reinforcements. You will need to check that everything is in line with the plans provided during the design stage. While this is not a common task ،
water infrastructure
Sanitary and hydraulic structures are not the same, while sewage pipes collect waste for disposal in places where human health will not be harmed, hydraulic constructions have a completely different purpose, hydraulic constructions aim to change the flow of water, which can be sewers or dams, and both It works to transfer water, and the obvious hydraulic structure is the dam, this dam combines the principles of energy saving for power generation and the use of civil structure
Industrial Structure Design
Structures used for industrial purposes are airports, warehouses, highways, dams, factories, power stations, etc. Typically, industrial infrastructure is set up to provide a direct product or service.
Industrial infrastructures are characterized by their enormous size and high investment requirements. The constructive design for the construction of industrial buildings plays a major role in societies and economies, and the planner must be aware of factors outside the environment but also social impacts.
Let’s give an example of a large warehouse for storing heavy machinery. In principle, this should be a simple structure. However, designers must follow a number of rules when choosing materials, such as: site temperature and other environmental conditions. The presented solution sometimes requires Considering catastrophic scenarios, such as when a machine hits a wall, part of the design analysis needs to consider such situations and ensure that the entire structure does not collapse, at least not immediately.

Living
This is one of the most common tasks. The structural design of apartments follows a series of regulations that vary by country, weather conditions, etc. Variables such as earthquakes, convection, snow and rain are calculated depending on the geographical location of the house.
And here we come to the end of the article, and it should be noted that each point above may require an understanding of various mathematical, mechanical and engineering concepts, and in many cases, structural engineers have to complete several specialized studies
