AbstractAbout AuthorsReferences
Due to the significant advantages of the structural, technological and economic nature of the pipe-concrete columns (PCC) have good prospects for wide application in the practice of construction. Pipe-concrete columns have high strength and rigidity with relatively small cross-sectional dimensions, economical, reliable in operation. However, their wide practical application constrains the difficulty of ensuring sufficient adhesion between the concrete core and the steel shell in places of transfer of loads to the column from the floors. The authors propose a method of improving the design of pipe-concrete column by use of self-compacting self-stressing concrete for concrete core, making it possible to increase the strength of contact between the concrete core and steel shell and to provide high-quality concreting of columns.
