The Influence of Dome Geometry on the Results of Modal and Buckling Analysis

The main purpose of this paper is to compare the results modal analysis for two types domes. first one a low-rise Schwedler dome. second high-rise geodesic dome subjected large displacement gradients and should be designed according geometrical nonlinear analysis. In case dome, linear sufficient. analysis, mass bars supporting structures was modeled as evenly distributed, while covering roof equipment concentrated in nodes. Classic calculations have been enriched with taking into account normal forces. Normal forces affect vibration frequency structure. Commonly used does not take influence order approximate actual working conditions structure, performed Autodesk Robot Structure Professional 2022 can accordance applied Additionally, stability loss verified using or buckling exigence including domes novelty message work.
