Structural engineering theory is based upon applied physical laws and empirical knowledge of the structural performance of different materials and geometries. Structural engineering design uses a number of relatively simple structural concepts to build complex structural systems. Structural engineers are responsible for making creative and ...
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
It also discusses the autonomy of the primary structure: "Many Structuralists would describe a structure roughly in the following terms: it is a complete set of relationships, in which the elements can change, but in such a way that these remain dependent on the whole and retain their meaning. The whole is independent of its relationship to the ...
In the context to structural analysis, a structure refers to a body or system of connected parts used to support a load. Important examples related to Civil Engineering include buildings, bridges, and towers; and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important.
The theory of structuration is a social theory of the creation and reproduction of social systems that is based on the analysis of both structure and agents (see structure and agency), without giving primacy to either. Furthermore, in structuration theory, neither micro- nor macro-focused analysis alone is sufficient
The term structural rationalism most often refers to a 19th-century French movement, usually associated with the theorists Eugène Viollet-le-Duc and Auguste Choisy. Viollet-le-Duc rejected the concept of an ideal architecture and instead saw architecture as a rational construction approach defined by the materials and purpose of the structure.
The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
In set theory, a mathematical discipline, the Jensen hierarchy or J-hierarchy is a modification of Gödel's constructible hierarchy, L, that circumvents certain technical difficulties that exist in the constructible hierarchy.
