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.

The existing regulatory documents on estimation of wave scours behind vertical-type structures take account of only frontal wave arrival. Though in most cases of real structures waves arrive at an angle to a structure. The kinematics of the formed wave field and as a result the interaction with the structure and the foundation soil differ from that of frontal waves. The work is devoted to investigation of local scour due to the influence of oblique waves. The main aim of the article is to define the features of the formation of the local scour due to oblique waves in front of breakwater and to define its difference from local scour caused by frontal waves. In order to study a local scour experiments have been conducted in a wave basin. As a result of the experiments the shape and depth of the scour were obtained. Significant differences of scour formation caused by frontal and oblique waves at the breakwater were found out. The scoured hole caused by oblique waves looks like a line directed along the walls, in contrast to the scour caused by the influence of the standing waves. It was found out that in case of smaller angle of wave arrival to the breakwater the depth and width of scoured hole increase. The experimental investigations also showed that the size of soil particles influence the formation of scour hole.
