Description
Summary:The object of this research is frame systems with concealed girders and flat floor slabs. The research helped identify the main advantages and disadvantages of precast/cast-in-situ frame systems for the construction of flat slab buildings using modular elements. The key methods used in the research were the analysis of the existing domestic and foreign technologies and the development of a new structural system differing from the systems discussed in the paper in terms of its technological intensity, versatility of application and rational design.The authors suggest a precast/cast-in-situ frame building system with concealed girders and flat floor slabs where the volume of modular precast elements drastically exceeds that of the cast-in-situ part of the frame. This allows for considerable saving in assembly and erection time due to a reduced number of process operations and modular assembly units. In order to identify the key benefits, the suggested frame system was compared with a KUB 3-V multi-purpose beamless frame system, which has been popular in Russia in recent years. Apart from a smaller number of process operations, the new system allows reducing the scope of welding and removing embedded parts connecting shells of drop panels with the bare part of column reinforcement. It also eliminates the needs for additional installation fixtures for columns and floor slabs, such as: support brackets and conductors for each column. The envelope of a building using the suggested frame system may consist of semi-integral thermopanels offered by domestic and foreign producers.
