Analysis of the Features of the Stress-Strain State of the Frame Tent Coating in the Calculation in Linear and Non-Linear Stages
Abstract: The object of research is a definition of the rational geometry of the long-span frame tent cover over stadium tribunes. Stadium is multifunctional with a capacity of 20 000 spectators. The coating frame is a structural plate supported by V-shaped pylon and a guy system. Two layers of fiberglass-based on polytetrafluoroethylene are used as protecting layers. In the proсess of research, rationalization of the geometry of a structural plate is done by using the method of reverse bending in several iterations to define outline of the plate. Moreover, in the article comparative analysis of the stress-strain state of load-bearing structural elements in linear and non-linear stages is preformed under the influence of the basic load combinations. The problem in a non-linear stage is solved by the finite element method using the Newton-Raphson method. Research completed using Autodesk Robot Structural Analysis.
Keywords: long-span structures, structural structures, frame tent structures, SSS, nonlinearity, CAD, reverse bend.
