ANALYSIS OF STRESS AND STRAIN IN THE REINFORCED CONCRETE STRUCTURE OF A SPORTS HALL GRANSTAND

The analysis of stress and strain in the reinforced concrete structure of a sports hall grandstand was conducted theoretically, by means of the finite element method, and experimentally, by structural model testing in laboratory. Structural model for laboratory testing was prepared on the scale 1:10 using a medium density fibreboard plate 38 mm in thickness. Mechanical properties of the medium density fibreboard were determined by testing medium density fibreboard specimens in laboratory. After analysis of the reinforced concrete grandstand structure, and following comparison of results obtained by model testing in laboratory with results obtained by analysis via finite element method, it can be concluded that there is a good correspondence of research results for stress and deflection of the reinforced concrete grandstand structure.
