Annotation: The paper presents an analysis of the actual work on the creep of concrete in the composition of a steel-reinforced concrete slab using a fixed formwork made of profiled sheet with dimensions in the plan of 20,5 m under prolonged static load without installing additional hardening and anchoring. An analysis of the test was carried out, the ultimate goal of which was to identify the ability of the slab to work, as well as to investigate the behavior of concrete within the slab body. Real changes in time of such characteristics as deflections and arising stresses on the slab surfaces are determined. The suitability of the steel-reinforced concrete structure according to the groups of limiting states has been determined. A comparative analysis of the results obtained with the data of regulatory documents has been carried out. Conclusions are made on the bearing and deformation capabilities of the structure under study under long-term static loading.
Keywords: experiment, slab, concrete, creep, load, efforts, deflection, stress.
