Golubova","doi":"10.37538/2224-9494-2022-4(35)-9-16","DOIUrl":"https://doi.org/10.37538/2224-9494-2022-4(35)-9-16","url":null,"abstract":"Introduction. At present, the overall production of light two- and three-layer wall panels and coatings having metal claddings and efficient insulation is continuously increasing in Russia. Especially relevant is the use of sandwich panels, since industrial and administrative buildings can be quickly erected, thereby significantly reducing their payback period. Regulatory documents regulating the production processes of panels were mainly developed in the 1970s and 1980s. However, over the past 40–50 years, much has changed in the technology of panel production, including the development of advanced materials for panel layers, new structural joints, and approaches to assessing the safety of panels. New federal standards for panel constructions and testing methods were developed in order to account for the changes in the intervening period.Aim. In this work, changes that occurred in the production of laminated panels are addressed, including changes in technical requirements for panel design solutions, butt joints, panel materials, methods of selecting and testing insulation and panels, and safety and environmental protection, in order to inform the manufacturers and consumers on the use of new documents in the production and application of panels.Materials and methods. When developing new regulatory documents (GOST R), the existing documents and results of panel testing at the TSNIISK named after V.A. Koucherenko were analyzed, along with the identification of new materials and technical solutions on the basis of the technical materials of manufacturing plants.Results. The work established current technical requirements for panel design solutions, butt joints, panel materials, methods of selecting and testing insulation and panels, and safety and environmental protection. The following new provisions are given in the developed standards: the scope of application and classification of indicators are expanded, more efficient butt joints for panels are recommended, the consumption of insulation material is reduced, and new methods of testing insulation materials are proposed.Conclusions. The implementation of the developed GOST R will optimize the manufacturing process of two- and three-layer panels having efficient insulation, along with reducing the labor intensity of their production.","PeriodicalId":169749,"journal":{"name":"Bulletin of Science and Research Center of Construction","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124147288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wood, being an affordable and renewable material characterized by high strength characteristics, is used in construction for both residential and non-residential buildings, as well as various structures. The strength and durability of buildings based on wooden structures largely depend on the strength and reliability of joints between wooden elements. At present, various types of nodal joints used in wooden structures all exhibit certain advantages and disadvantages, calling for an improvement and development of new types of joints having high strength and manufacturability.Aim. In this work, the behavior of an improved joint of wooden structures using insert steel washers was investigated, along with the development of their manufacturing technology and methodology for studying.Materials and methods. The investigation of the joint involves manufacturing a series of samples and conducting an experiment in order to determine the load to failure and ultimate strain.Results. The manufacturing method of a joint and the experimental procedure were developed; values of load to failure and deformation were determined experimentally, with the deformation curves being plotted. It was revealed that the threaded connection of an insert steel washer and a rod leads to a decrease in the bearing capacity of the joint due to the thrust occurring in the adhesive line. In addition, it was established that the parameters of the steel washers affect the joint behavior.Conclusion. Experimental studies of the joint showed that the threaded connection between the rod and the insert steel washers fails to increase the bearing capacity and stiffness of the joint due to the early failure of an adhesive line and the separation of the washers from a wooden element. However, using additional joints that accept the thrust in the connection can solve this problem. It is necessary to conduct additional research in order to assess the feasibility of using such a connection.","PeriodicalId":169749,"journal":{"name":"Bulletin of Science and Research Center of Construction","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122387431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mechanism of the formation of snow deposits on the shell of the Luzhniki GSA and their redistribution in winter were established on the basis of the data obtained during the monitoring of the snow load for over 20 years.Aim. In this article, the mechanism of the formation of snow deposits and their distribution on the shell of the Luzhniki GSA were determined, along with the numerical values of the form factor μ characterizing the transition from the ground snow load to the snow load on the shell.Materials and methods. The measurements of the load and density of snow deposits on the shell of the Luzhniki GSA were carried out from 1998 to 2019. The obtained results were compared with the parallel measurements of ground snow load (GSL) in Luzhniki. In addition, the snow load, as well as statistical data analysis on the maximum annual values of the GSL, were analyzed using the hydrometeorological data of decadic snow surveys in Moscow, performed by the V.A. Mikhelson Meteorological Observatory following the dates of field measurements. The graphs of the repeatability of wind directions for the month preceding the observation dates were plotted.Results. The maximum values of the form factor μ for each section of the shell were obtained. The areas characterized by increased snow deposition on the shell during various periods of snow accumulation andthe dependence of their formation on wind speeds and directions in winter were revealed. Graphs depicting the distribution of snow load on the surface by observation years were plotted. It was established that the values of snow loads on the GSA shell during the observation period generally lay within the design values, except for local zones near the internal contour during the installation of the canopy.Conclusion. It was shown that the formation, accumulation, and redistribution of snow deposits on the shell comprise a complex and uneven process, varying from winter to winter. When selecting the analytical models of snow loads for calculating unique load-bearing structures, it is necessary to account for the most unfavorable wind flow directions, at which an uneven snow deposition pattern occurs, as well as the physical properties of the shell and field observations.","PeriodicalId":169749,"journal":{"name":"Bulletin of Science and Research Center of Construction","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129236756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
