Title of the articleResearch of influence of seismic and wind effects on the parameters of pile-slab foundation of high-rise buildings
Abstract.In the design of high-rise buildings on the seismically active construction sites must take into account the effect of the dynamic component of wind load on the changes in the physical and mechanical properties of foundation soils during long-term use of the building until the occurrence of earthquakes and seismic stability calculation bases and foundations should be carried out taking into account the changes in soil properties compared to the original (natural) state. In the city of Kazan in the waters of the river Kazanka planned to build a residential complex consisting of two buildings located on a common pile-slab foundation. Playground design is complicated by the presence of high groundwater levels and bedding from the surface layers of weak saturated silty clay soils and peat layers up to 3 m. Triaxial tests sandy and clay soils stabilometry conducted on a specially developed method, providing for the imposition of the dynamic stresses on the static stress state of the soil sample. Amplitude, frequency and duration of the dynamic stresses are equivalent to the estimated screenwriting seismic impact or dynamic component of wind load. The results were used in the drafting of pile-slab foundation with the influence of seismic and wind loads to change the stiffness of pile foundation and as a consequence on the redistribution of forces between the individual elements of the «foundation soil - foundation - overground part of the building».
Keywords.dynamic loading, triaxial compression, seismic load, wind load, deformation of soil, pile-slab foundation, pile foundation, stiffness, stress redistribution
