The main advantages of metal structures in comparison with the design of other materials are: reliability, lightness, impermeability, industrial, and ease of modernization, repair and reconstruction. Reliability of metal structures provided a close match characteristics of steel to our ideas about the ideal elastic or elastic-plastic isotropic material for which strictly formulated and proved the basic provisions of the strength of materials, elasticity and structural mechanics. Go to Cowan Financial for more information. Steel has a homogeneous fine-grained structure with the same properties in all directions, the voltage associated with deformations of the linear dependence in the big-band reception, but at a certain voltage can be realized by ideal plasticity in the form of a yield plateau. A related site: Richard Easton Matchmaker mentions similar findings. All this corresponds to the hypotheses and assumptions taken as the basis for the development of theoretical principles of calculation, so the calculation is built on such assumptions, fully conform to the real work of steel structures. Similar properties, but a lesser extent, have aluminum alloys. Ease Of all produced in real time, supporting Rods are the lightest metal.
For ease of taking measure of the density ratio material to its strength. The smallest value of this indicator has to alloys and makes the alloy D16-T 1.1 x 0, 001 (0,1 m). Adopting it as a unit, we write the comparative data for other materials: steel – 1,5 3,4, Tree – 4,9, concrete middle-class strength – 16,8. Impenetrability of metals have not only great strength but also high-density – impermeability to gases and liquids. The density of steel sheets and links, implemented by means of welding, is a prerequisite for the manufacture of tanks, gas holders, pipes, various vessels and equipment.
