Nosenko V. Stress-strain state of pile-raft foundation section of high-rise buildings

The object of study - the interaction of pile foundations sectional high-rise buildings with ground base. Purpose of the study - the stress-strain state in the elements of the "base-bases, aerial construction" at various stages of construction and redistribution efforts in pile foundations taking into account mutual foundations sectional high-rise buildings. Purpose - to develop a method of calculating the mutual influence of neighboring buildings on the basis of numerical modeling of the stress-strain state of "basement-foundation-aerial construction" and predict the impact of new construction on surrounding objects. Methods: engineering calculations estimation of interference foundations under existing regulatory methods and modeling of pile foundations using the numerical simulation of the stress-strain state of "basement-foundation-aerial construction" instrumental observation of deformation structures of buildings on experimental grounds. Novelty - discovered a new effect of the sequence of construction of sections for redistribution efforts under piles in the area of the junction sections tall building that is unloading piles sections, built earlier and increase the load on the pile section is structured as follows. The properties feature distribution efforts in piles foundations sectional high-rise buildings is slack in peripheral piles and piles to increase efforts in the central area taking into account the mutual influence of the bases adjacent sections, the behavior of the bearing structures multisession high-rise building in the zone of deformation seam and shows that its presence reduces the load on the piles and columns of low-rise and increased pressures on them in high-rise section. Industry - construction.
