【 摘 要 】

Performance of statistically undefined reinforced concrete constructions in harsh weather conditions is characterised by the presence of temperature forces. The strength of temperature forces is influenced by deformation and durability qualities of the concrete, crack formation and pliability of supports. Experiments were carried out in order to establish correlation between support pliability and temperature forces in bendable reinforced concrete elements in the conditions of limited mobility of supports. The result of the present research was experimental data on the changes of temperature forces depending on the horizontal pliability of swivel supports. Analytical dependency was suggested to calculate support pliability and change rigidity of reinforced concrete beams under the influence of load and low temperatures.
