Szukana fraza: [Abstract = "The interaction of piles with different lengths and the grillage in the foundations of high\-rise buildings is considered. The numerical modeling of the \?base \- foundation \- superstructure\? system is performed. The redistribution of the efforts in piles depending on the sizes of a foundation slab and the parameters of piles \(length and location\) is investigated. Typical zones of a foundation such as central, lateral, and angular ones are separated. The redistribution of efforts between piles and a grillage is revealed."]
