Abstract
Изобретение относится к области строительства, в частности высотных зданий и грузонапряженных мостов, а именно к способам повышения прочности трубобетонной конструкции на основе достижения известного «эффекта обоймы», возникающего в результате стеснения (ограничения) поперечного расширения бетона при сжатии. Суть способа в том, что при заполнении трубы бетоном и образовании бетонного сердечника между ним и внутренней поверхностью стальной трубы создается продольный деформационный промежуток, достаточный для свободной боковой деформации бетонного сердечника при его первоначальном нагружении до предела прочности при одноосном сжатии. С целью обеспечения раздельного учета возможных продольных деформаций бетонного сердечника и стальной трубы продольную сжимающую нагрузку на трубобетонную конструкцию начинают с нагружения бетонного столба и после достижения его усадки на величину продольного деформационного промежутка продольную сжимающую нагрузку распространяют и на стальную трубу.The invention relates to the field of construction, in particular high-rise buildings and cargo-stressed bridges, and in particular to methods of increasing the strength of the pipe-concrete structure based on the achievement of the well-known "cage effect" resulting from the constraint (limitation) of the lateral expansion of concrete under compression. The essence of the method is that when the pipe is filled with concrete and a concrete core is formed between it and the inner surface of the steel pipe, a longitudinal deformation gap is created that is sufficient for free lateral deformation of the concrete core during its initial loading to the ultimate strength under uniaxial compression. In order to ensure separate accounting of possible longitudinal deformations of the concrete core and steel pipe, the longitudinal compressive load on the pipe-concrete structure begins with loading the concrete column and after reaching its shrinkage by the magnitude of the longitudinal deformation gap, the longitudinal compressive load is distributed to the steel pipe.
