Comparative analysis of the design and technological parameters of foreign precast-monolithic systems of civil buildings. Part II

The process of multi-storied prefabricated monolithic civil buildings construction is a set of technological operations which require high-quality preparation and organization of production. This is important both during manufacturing and transportation of prefabricated structures, and during their installation in the building conditions. At the same time, the technology of prefabricated-monolithic construction has several important advantages, allowing the developer not only to reduce employee labor and machine work of construction processes at the site, but also increase the construction speed of the building framework, as well as its quality, when compared with the monolithic execution. These advantages ensure the demand for this technology when the developer chooses the rational option of a civil building erecting. The object of research - prefabricated monolithic frame systems (PMFS) in foreign construction projects. A comparative analysis of 17 foreign PMFS developed over the past 70 years in the USA and some European countries was performed in order to determine the methodological tools for the selection and implementation of the most promising PMFS. A further aim was to improve the design and technological parameters of the domestic civil engineering PMFS and increase their practical application. The present article which continues the publication series devoted to the foreign PMFS of civil buildings contains the results of the comparative analysis of the system technological parameters. Open source information was taken as the initial data. As a result of the analytical study, a set of characteristic technological parameters and their values were determined for each PMFS. The information obtained is presented in the clear tables, allowing for an evaluation of the variability of characteristics for transportation, installation and additional construction the load-bearing structures work of PMFS. The analysis also revealed some regularities in the development of prefabricated-monolithic systems.
