Spirals\u00ae: innovative structural solutions"},"content":{"rendered":"<p>The current deficit of the <strong>ecological supply chain<\/strong> is the lack of attention to <strong>material consumption<\/strong>, which makes it, more often than not, <strong>ineffective<\/strong>.<\/p>\n<p>During design and construction it therefore becomes fundamental to <strong>respect sustainability<\/strong> in its rules, such as the <strong>lowest possible use of materials<\/strong> (direct eco-sustainability), given the limited resources in the world, and to choose <strong>low-polluting production processes<\/strong> to favour disposal in accordance with the life cycle of the materials, with the recovery of green energy.<\/p>\n<p>It is from this principle that <strong>Crossed Spirals\u00ae<\/strong> was born, thanks to the idea of the <a href=\"https:\/\/www.studiorosasco.com\/\" target=\"_blank\" rel=\"noopener\">architectural firm Enrico Rosasco<\/a>: its

style=\"font-size: 8pt;\">Presentation of the Crossed Spirals structural principle then applied to a real case.<\/span><\/p>\n<p>&nbsp;<\/p>\n<h2>What&#8217;s the Reticular Structure of Crossed Spiraloid Lines<\/h2>\n<p>Conventional buildings consist of an upper roof supported by a plurality of columns\/pillars: they lack the efficient weight-relieving characteristics of the upper structure and are not sustainable.<\/p>\n<p>Crossed Spirals invented a building of the industrial shed or similar type, comprising an upper roof and a support system resting on the ground, configured to unload the weight of the upper roof.<\/p>\n<p>The column&#8217;s constituent elements recall the behaviour of a tree trunk in which the stems (which become branches once they dissociate geometrically from the stem) form a series of small channels that transport sap from the roots to the leaves.\u00a0 This plurality of small channels make the tree a pre-tensioned structure whose main characteristic is its ability to absorb stresses from the canopy (crown).<\/p>\n<p>Based on what has been described, it is evident that the building allows for an <strong>efficient direct discharge of stresses to the ground<\/strong>, as well as an even <strong>distribution of loads<\/strong>, achieved through direct dissipation of energy through only axial stresses and a rapid transport of stresses to the ground.<\/p>\n<p>The starting point for the realisation of the Crossed Spiral Line Reticular Structure is the mathematical study of <strong>gold distributions<\/strong> derived from the <strong>Fibonacci sequence<\/strong>, followed by the study of <strong>energy dissipation<\/strong> solutions within natural structures, the study of <strong>convective air movements<\/strong> derived from the thermal gradient (Computational Fluid Dynamics), and finally the study of thermal insulation of buildings.<\/p>\n<p>The structural method <strong>Crossed Spirals \u00ae<\/strong> bases its approach on an <strong>equilibrium of stresses generated by actions:<\/strong> the crossing of spirals is the best way to achieve this equilibrium in which the stresses generated must be brought to earth in the most essential way, without generating other superfluous and harmful stresses.<\/p>\n<p><strong>Spirals<\/strong>, in geometric terms, have a unique characteristic that can also be found applied in <strong>nature<\/strong>: in the principle from which galaxies are generated, in the growth of a flower, in the development of cells and the waves of the sea, to name but a few examples.<\/p>\n<p>&nbsp;<\/p>\n<div class=\"btx-item js-item-gallery btx-gallery btx-gallery--carousel\" data-popup=\"true\"><div class=\"btx-gallery-content\" style=\"margin:0 0px;\"
