A comparative analysis of foundation design solutions on permafrost soils

Abstract

The article analyzes design solutions of foundations on permafrost soils, their advantages and disadvantages. Innovative design solutions that increase the energy efficiency of buildings are proposed. Examples of innovative foundations of platform type are given. Spatial ventilated foundations are less sensitive to soil deformation. The construction of such a foundation can be made of various materials such as reinforced concrete, metal and timber. A spatial foundation platform based on timber is proposed as one of the innovative examples, which is a promising constructive solution of foundations for construction in the Arctic regions. Wood has a small coefficient of thermal conductivity, which significantly increases the energy efficiency of the structure as a whole. Due to prefabrication of timber structures, the speed of construction is increased. Platforms can have solutions in the form of: system of cross beams, structural plates, plate-rod structure, as well as in the form of shells and folds. Regardless of the design solution, the spatial foundation platform is prefabricated.

Early Signs of Swamp Building Collapse: Failure of Wood Pillar Foundation

“…Foundation engineering concepts can be used to analyze its strength [13,14]. Innovative timber-based spatial foundation platforms offer even settlement in swampland, can be strengthened for modern use, and offer local suitability but lack detailed geotechnical design [15][16][17]. The historical wood pillar foundation is a crucial load-bearing element in buildings, utilizing used wood for foundation, roofs, columns, and beams, ensuring safety and stability [18][19][20].…”

“…DOI: 10.31675/1607-1859-2022-24-4-99-109 Структурные конструкции находят всё больше вариантов применения при строительстве современных зданий. В последнее время структуры охотно используются архитекторами и инженерами для спортивных залов, стадионов, культурных центров, аэровокзалов, промышленных зданий, гаражей и анга ров, в высокоширотном строительстве [1]. Такую популярность можно объяс нить естественными преимуществами данных пространственных конструк ций, которыми не обладают традиционные рамные и каркасные системы.…”
