In the recent years there appeared a tendency of widening the use of composite reinforced concrete structures in Russian construction practice, which keeps current the further investigations of their stress-strain state. In order to estimate the stress-strain state of composite reinforced concrete structures different methods are used: both analytical and experimental. In spite of material and labour costs field tests give the most correct indexes of the behavior of structures in actual operating conditions. The experimental investigations of composite reinforced concrete floors of civil buildings having considerable slenderness allow exploring new qualitative data of their stress-strain state. The authors offer the analysis of experimental investigations of composite reinforced concrete structures, in particular, composite reinforced concrete floor. They described geometrical and physical parameters of a test piece, the methods of measurements and tests, the experiment’s results are analyzed. The charts of flexure, stress blocks and distribution of moments are offered. The authors also give the results of numerical experiments and comparisons of stress-strain state of composite reinforced concrete floor with the results of field tests and their analysis.
