Mechanics Building Materials
A single object created by a person is called structure. Buildings are necessary to meet the vital needs of the people and to improve their standard of living. They must be comfortable, durable, stable, and safe.
Structure construction forms one of the most ancient occupations of man and ancient art. Evidence of the excavation of many ancient monuments in different parts of the world, ancient structures, and buildings preserved to this day. Their perfection and beauty speak to the great experiences of art and ancient builders, even for modern knowledge.
Building mechanics is often called structural mechanics, dealing with the calculation of specialized science structures. Independently as a science, the development of building mechanics began in the first half of the 19th century about the active construction of bridges, railways, dams, ships, and large industrial structures. Over the centuries, as a result of the development of calculation methods and computer technology, building mechanics have risen to modern high levels. The lack of calculation methods for such structures did not allow for the implementation of lightweight, economical, and at the same time reliable structures.
It is believed that construction mechanics emerged after the publication of the work of the great Italian scientist Galileo Galilei in 1638. "Conversations and mathematical proofs about two new branches of science related to mechanics and the local movement ...".
Several of his researches on the bending resistance of beams are valuable today. However, he failed to make a complete theory of bending the beam, as he mistakenly believed that all fibers stretched during beaming. Furthermore, no connection was made between the strains and the strains at that time. Later, r. Hooke (1787878), this law was made in its simplest form: the expanded key - this is energy, later "in the second half of the eleventh century." Bending leads to problem-solving. The most important factor in the development of mechanics was the success of higher mathematics, the work of Euler and Lagrange.
Stable development involves the development of methods for computing on indefinite systems, for example, B.P. Clapiron (three-moment equation for continuous ray calculation), J.K. Maxwell, and O. Mora (determination to displace the elastic system by the given internal forces). By the 30th year. When reached perfection in the calculation of elastic statistically indeterminate systems, the main methods of calculation were distinguished: the force method, the displacement method, and the mixed method, as well as their numerous modifications.
The first Russian scientist M. Lomonosov became interested in energy issues, in particular, because the energy conservation laws he enacted were one of the fundamental mechanisms of structural mechanics. Based on this, a universal method for determining displacement was developed.
A significant contribution to the development of mechanics, especially in the field of experimental methods, was made by the Russian mechanic I. Kulibin (1733 - 1818). He created a project of an arched wooden bridge of 300 meters long across the Neva when he first applied the rule of force rope polygons in the calculation of forces. One of the brightest projects of the metal bridge is also II Kulibin. He proposed it as a three-arch system.
The theory and practice of bridge-building was further developed in the works of D. Zahuravsky (1821 - 1891). He developed the theory of calculating flat firms. He also developed the theory of sensitive pressures during bending.
Significant contributions to the formation and development of building mechanics were made by H.S. Golovin (1844-1904) (Calculation of arches and curved rods using the method of elastic theory), N.A. , Publication of courses on structural mechanics), F.S. Yasinsky (186-18-1999) (Study on Rod's theory of stability), VL Kirpichev (18 185-191)) (Mill's law, the great textbook on structural mechanics).
End of - beginning of c. Significant contributions to the development of mechanics A.N. Krylov (ship theory, approximate method of solving mechanical problems), SP Tymoshenko (problems of turning and position theory, problems of plate and shell theory, outstanding textbooks that could not lose them as world-renowned scientists did. Standards at present), G.V. Kolosov (the plane problem of the theory of elasticity), IG Bubnov (variable method), BG Galarkin (theory of plates and shells, approximate method).
Notable engineers, academics V.G. The statics of the structure were extensively worked on by Shukhov (1853-1999). Hyperboloid openwork towers, bulk river, and sea ships, net arches spread all over the world due to its talent. He now laid the foundation for the development of the field of structural optimization - related to structural mechanics.
