The work is devoted to the study of the possibility of using transverse reinforcement to increase the bearing capacity of masonry from aerated concrete blocks and the development of a calculation method that allows to quantify the proposed reinforcement. The need for the formulation of such studies was due to the lack of regulatory data regarding the reinforcement of the masonry concrete blocks, as well as an increase in production volumes and demand for cellular concrete. The results of experimental studies of masonry of aerated concrete blocks, reinforced by welded meshes under the short-term action of axial compressive loads are presented. The effect of increasing the carrying capacity due to the constraint of deformation of the masonry due to transverse reinforcement is revealed. The reinforcement rods of welded meshes, located in horizontal mortar joints, possessing a much greater modulus of elasticity than the masonry, prevent the development of masonry deformations in the transverse direction and, thereby, create lateral compression stresses. The proposed and experimentally confirmed by the authors method of increasing the carrying capacity of compressed elements, based on the principle of transverse (indirect) reinforcement of stone materials, can be applied to the laying of concrete blocks.

In this article discusses the mechanical properties of foam concrete, which submitted based on the experimental data of long force resistance and deformation of compression elements from foam concrete. Also submitted criterion range of strength and deformation characteristics of foam concrete different structural modification with taking into account the permanently acting load, which necessary for calculation and design structures of buildings. In article such characteristics of foam concrete as durability and deformability at the age of 28 days by results of short-term tests and also influence of average density and a type of structure on its durability and deformability are considered. Change of mechanical properties of foam concrete in time by results of short-term tests is analyzed and studied. Experimental and theoretical researches which have in turn allowed to recommend for rationing of value of settlement characteristics the foam of concrete taking into account their variability, aging and duration of action of loading are executed.

Существующая на мировом уровне заинтересованность в арктических территориях требует нового подхода в проектировании, что обеспечит устойчивость данных регионов. В связи с этим обсуждается актуальность применения конструкции двойного фасада в холодном климате. Данная конструкция малоизучена и требует научного обоснования. Проведено исследование влияния ширины буферной зоны двойного фасада на результаты теплотехнического расчета двумерных температурных полей. За базовый регион для последующего расчета был выбран арктический город Мурманск. Исследовано шесть вариантов конструкции узла «перекрытие – наружная стена». Теплотехнические расчеты по каждому из вариантов выполнены с помощью программного обеспечения Elcut Student 6.4. Результаты расчетов сведены в единую таблицу. Найдена взаимосвязь ширины буферной зоны и теплопроводности конструкции двойного фасада. Сделаны выводы и выделены перспективы развития данной конструкции в холодных регионах.
