  Structural Design - Methods
The goal of structural design is to determine the number, material composition and thickness of the different layers within a pavement structure required to accommodate a given loading regime.
Structural design is mainly concerned with determining appropriate layer thickness and composition.
In pavement design, the phenomena are the stresses, strains and deflections within a pavement structure, and the physical causes are the loads and material properties of the pavement structure.

  Structural engineering - Wikipedia, the free encyclopedia
Structural engineering is the field of civil engineering particularly concerned with the design of load-bearing structures.
Structural engineers need to design structures so that while serving their useful function, they do not reach collapse (structural failure or ultimate limit), and do not bend, twist, sag or vibrate in undesirable ways (serviceability limit).
The sum of the forces acting on the structure are equal to the sum of the supporting reactions - the forces acting on the structure are in equilibrium.

 Aircraft Structural Design
Although the major focus of structural design in the early development of aircraft was on strength, now structural designers also deal with fail-safety, fatigue, corrosion, maintenance and inspectability, and producability.
Modern aircraft structures are designed using a semi-monocoque concept- a basic load-carrying shell reinforced by frames and longerons in the bodies, and a skin-stringer construction supported by spars and ribs in the surfaces.
For the best current methods of design, a scatter factor of 2 is typically used, so that the expected crack-free structural life is 60,000 hrs, and the probability of attaining a crack-free structural life of 60,000 hrs is 94 percent as shown in the following figure and table.

In civil engineering Structural design is a reiterative process of applying engineering mechanics and past experience to create a functional, economic and, most importantly, safe structure for the public to enjoy.
Using structural analysis techniques and comforming to design specifications the design engineer works to create a solution that is to everyone's benefit.
Sadly, structural design is also a process that has evolved to its modern refinement through hard lessons.

 Design Considerations for Fire Resistance of Structural Strengthening System
Compared with normal temperature design, the behavior and rating of the structural member (existing or upgraded) at the time of fire is different because the applied loads are smaller, material strengths may be reduced, smaller load factors can be used, and serviceability requirements are not important.
As a result, the strength design of a structure for fire safety is different than that for ultimate capacity and may incorporatelower material strengths and load factors and no strength reduction.
The additional concrete may be "structural" concrete reinforced with steel bars or wire mesh and designed to be a load-carrying element, or "protective" concrete used to increase durability, fireproofing, or to encase post-tensioning or bonded steel elements to protect them from mechanical and environmental damage.

 PB Network | Issue 36 | Tips for Slurry Wall Structural Design
Design of a slurry wall is greatly dependent on the method of analysis used and requires close communication between structural and geotechnical engineers.
The slurry wall was designed for soil, groundwater and surcharge pressures in all three stages, and for seismic pressures in the long-term stage.
As structural engineers, we must acknowledge that the ultimate performance of the slurry wall is more significantly affected by construction techniques and site-specific subsurface conditions than it is by the structural details and code interpretations.

 GoStructural.com - Blast-resistant design for buildings
Structural engineers who may not have experience in blast-resistant design need to recognize how these complex requirements interface with typical structural design, and coordinate them with architectural requirements.
Design models must account for this condition, and solutions include increasing the beam depth, decreasing the column spacing, requiring more bottom reinforcing to be continuous over the columns with laps staggered, and increasing the quantity and length of top bars.
Finally, the structural engineer not only must account for these blast effects, but also he or she must coordinate these issues proactively with the design architect and other engineering disciplines that may be affected by changes in the building structural elements.

 Visual Vs. Structural - Accessites.org
Structural designers start with the content, making sure that everything is marked up semantically and that there is a logical order to it.
Visual designs that rely heavily on background images tend to have a fixed width where the dimensions of the various areas on the page are specified in pixels.
A page created by a visual designer may also have a logical source order, but with a complex graphic design it is not uncommon for the content to be split into less than logical parts when it is coerced into a structure emanating from the visual design.
