Study of General Stability of Large-Span Pipe-Concrete Arch Structures
Journal Title: Металлические конструкции - Year 2018, Vol 24, Issue 2
Abstract
The results of analysis of general stability of long-span shotcrete of the arched coverage are presented in the article. A calculation is produced in a calculable complex LIRA-SAPR 2013. The main purpose of work was determination of coefficient of supply of stability and forms of loss of stability, and also comparative analysis of the obtained results for the arches of continuous and through section. For this it was engineered the design scheme of tube-confined concrete arches of solid section, it was created a model of an arched cover and the concrete pipe model of the arch end-to-end cross-section of rod finite elements. This allowed to analyze in detail the form of the loss of stability and the factor of reserve, as well as to assess the stability of the arched cover with regard to the release of connections and runs. According to the results of the calculation, economic comparison of two types of arch structures was made.
