Development of Constructions and Technologies of High-Precision Installation of Pipe Concrete Columns of Kinematic Systems of Seismic Protection of Civil Buildings Frames

Abstract

Summary. Seismic isolation systems of kinematic type, selected as promising ones, first proposed in the former Soviet Union by Professor Yu.D. Cherepinsky, are considered. This technology was further developed in the works of Professor A.M. Kurzanov, who introduced his developments at the facilities of the Krasnodar Territory of the Russian Federation. However, the analyzed innovative domestic technology is not without its drawbacks. Subject of research: the design and technology of seismic isolation of overground floors of civil buildings using kinematic systems made of pipe-concrete columns. Materials and methods: analysis of the state of the art with a description of the positive and negative aspects of the existing technology, substantiation of the ways of possible progressive development of structures and technology of seismic isolation systems of the kinematic type, increasing the reliability of their operation under seismic load. Creation of graphic models of the nodes of support of concrete columns, implementing the intended directions in specific design solutions and technology for their implementation. Results. Patented designs of joints for pivotal support of pipe-concrete columns of kinematic systems for seismic isolation of frames of civil objects and a technological scheme for their alignment and high-precision installation. Conclusions: New design solutions have been proposed for the joints of the hinged support of pipe-concrete columns of kinematic systems of seismic isolation, as well as an improved technology for their installation, implying an increase in the reliability of their long-term operation in areas of high seismic activity.
