REGULARITY OF PIPELINE PILLARS DESIGN SCHEMES DURING THE SEISMIC RESISTANCE ASSESSMENT

Abstract

Purpose. To submit recommendations to the visual evaluation of such type of structures on the basis of an analysis of existing freestanding pillars for technological pipe lines of the real objects and their strenthening by ensuring regularity. Methodology. The combination of numerical calculation methods (finite element method, implemented in the software complex Lira) and the method of expert estimations. Seismic resistance estimation and maintenance of existing freestanding pillars of technological pipelines. Findings . Obtained strengthening circuit designs that provide the requirements of both groups of limit states, the results are summarized in order to further visualize assessment of seismic stability of such structures on the basis of the presence and amount of bond elements. The proposed method of strengthening is relevant is the temperature dependence of the configuration of pipelines blocks. Originality. The approach proposed as a result of the visual evaluation of seismic stability of pillars for technological pipelines is the first step in the implementation of the developed evaluation systems of actual seismic resistance of buildings and structures, which is currently being developed for the reinforced concrete frame buildings. Practical value. Constructive solutions to strengthen pillars to ensure regularity of individual thermal units made on the basis described in the work of the results are realized
