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

Application of precast-monolithic construction technology currently accounts up to about 10% of the total building volume despite a number of undeniable advantages which it has as compared to monolithic and precast house construction. To enable the development of methodological tools for the selection and application of the most promising precast-monolithic frame systems, as well as to improve the design and technological parameters of Russian precast-monolithic frame systems for civil buildings, and to increase the scale of their practical application, a comparative analysis of 17 foreign precast-monolithic frame systems developed in the USA and several European countries over the past 70 years has been presented in a series of publications. In this article, which opens the series of publications on foreign precast-monolithic systems for civil buildings, the results of the comparative analysis of systems by design parameters have been presented. Information from open sources has been taken as initial data. As a result of the analytical study, a set of characteristic design parameters and their values has been determined for each precast-monolithic frame system. The obtained data are presented as tables, allowing to assess variability of the characteristics of the supporting structures of each precast-monolithic frame. As a result of the conducted analysis, certain patterns in the development of design parameters of precast-monolithic systems have also been revealed.
